 Okay. Thanks, Brad. And welcome, everyone. It is great to see so many people here for the first in-person or at least semi-in-person systems all hands meeting since 2019. I'm going to keep this short. I want to just share a couple of updates from the integration facility, touch on a couple of logistical points and say just a few more words about the theme for this year's meeting. This is actually not the set of slides that I think that I think we need. But that's okay. We'll go with it. Okay, well, then my bad. I guess I did. Okay, that's fine. No problem. So let me, let me comment first of all on the theme of environmental extreme so about eight weeks ago I was on an airplane that was just touching down at Denver Airport. It's only the second airplane trip I had taken in since the pandemic started and looking out to the West there's a plume of smoke rising over what looks like my neighborhood. So when my wife and I turned our phones on, there's a string of text messages saying things like, we have your cat, and you have to evacuate now. So we were lucky our neighborhood was fine nobody was hurt, no structures were burned but it was a visceral reminder that each year, a lot of humans on this planet are not so unscathed in their encounters with various kinds of geophysical events and of course that's one of the motivations to study these things right that's one of the motivations to understand the processes behind floods and landslides and coastal storms and whatnot. But there's more to it than that as Brad alluded to right that we know that these events are part of a tapestry processes that shapes earth scapes sedimentary basins landscape seascapes over time and that's one of the things that that our community is interested in as well. So let's zoom out for a moment and think about the broader geological tapestry. In fact, you can view longer term processes as being a kind of environmental extreme as well so think about ice ages. Think about times of especially high or low sea level. Think about the paleocene is seen thermal maximum, even some tectonic events think about a mantle drip is in sent in some sense an environmental extreme right. So metaphor think about plate boundaries these are zones in space of extremely concentrated geophysical activity. And one thing that that different tapestry of processes has in common is the fact that almost none of them, maybe none of them at all fit comfortably in the confines of the laboratory right it's not easy to do experiments on these geophysical and environmental systems that we study. So what do we do we turn to computational models to be able to conduct controlled experiments, and also as containers of our theory right these are our ideas written in the form of equations and algorithms that we're iteratively comparing with nature, and hopefully improving. Okay, so the theme of computational modeling that's one of the key things that brings us together here as the CSDMS community. For those of you new to CSDMS the acronym stands for the community surface dynamics modeling system. It is a community and an NSF sponsored facility so I want to make sure that we express our gratitude to the National Science Foundation supported CSDMS and his community for a long time. The mission of the facility is to support the research that you all do in computational research on the earth and its surface processes and near surface processes. We do this through three main areas of activity there's community support various kinds of computational support hardware access software tools and protocols, and various kinds of educational resource and programs. So I'm going to just flip through a few quick updates from the integration facility so starting with. Let's see we'll start with the model repository so many of you are familiar with the model repository. This is a catalog of community shared model codes ranging from single sub routines to big integrated numerical models. There's now over 400 of them and that's a lot to sift through if you're a model shopper so we've added some new capabilities for dynamic search. We've begun tagging models if their code has been explicitly peer reviewed. There's also an extensive bibliography. There's also references to papers by about or describing applications of particular models, and that helps give you information that you can use to evaluate for example, is this particular code being published about frequently, how well used is it in a community. Another feature of the model repository that you that's not visible on the website but is no less important is hot off the presses they're now embedded micro tags that make the model database much more easily searchable by, for example, Google being in your favorite search engines. Let's see. In terms of support to individual researchers we continue to provide access to research software engineers who can help you with your work. There is a help desk where you can post technical questions and get answers from the engineering team. There is a, the possibility of consulting one on one with the research software engineers if you have questions that or or ideas that you want to talk through we can help you for example talk through ideas for broader impacts on a proposal. So you can contact us about that at CSDMS at colorado.edu. Let's see another resource that I'm delighted to announce today is the debut of open Earthscape. So this is a project that is also supported by NSF, and it is about developing the next generation of the CSDMS workbench tools. And one of the key tools in that tool kit that has rolled out in the past few months is the open Earthscape Jupiter hubs. So this is a pair of cloud hosted server resources where you can log in and get access to Jupiter notebooks and associated tools right so many of you are familiar with Jupiter notebooks is these wonderful documents that provide code and text and graphics and animations and so on. So there are two of these. One is called Jupiter dot open Earthscape dot org that's designed for research. And there's a second one called lab dot open Earthscape dot org that is for classrooms clinics workshops and things like that and some of you will have the chance to experience that firsthand later today or later this week. Another of the products that system supports is land lab. So land lab is, as many of you know a Python language programming package and library that is designed to make it easier more efficient to create integrated numerical models of various kinds of processes. So this slide shows snapshots of some examples. Actually, this one doesn't show that this is several examples of papers that have been published using land lab. So applications from dry land hydrology to tectonic geomorphology to frog ecology was one that I thought was kind of interesting. So it's a variety of different things. Land lab version 2.5 has just been released. It has some new components there's a like a marine carbonate producer component. There's a couple new flow routing components and some other things so I encourage you to check that out. Okay, next up another tool in the toolkit are is or our data components. So data component is a piece of Python software that allows you to access a particular data set and subset it if needed, from a remote location. Currently so the idea is that you have your, your data access and processing as a scripted part of your workflow. So data components they do things like they that's atmospheric data soils data USGS stream flow data national water model output topography from our friends at open topography, and even a generic geotip file reader. So, check those out there are tutorials online both accessible both through the systems web portal and through hydro share. Let's see what's next the basic model interface. So, some of you are users of the basic model interface. This is an interface standard for grid based numerical models. And essentially in English what that means is, it's a list of functions, which if you attach it to your model your model gains a degree of interoperability and standardization that make it easier to work with and easier to connect with other models and kind of coupled modeling. So it's now in use by a variety of groups, not just in the US but overseas as well. And in many ways it started to outgrow just our small integration facility team here in Boulder so we'll be later today, kicking off the inaugural meeting of the BMI Council. This is a group of BMI users who have generously volunteered their time to help steer and guide the future of this evolving standards so thank you to all of you. Okay, turning now to some educational resources. Our collection of online labs about models and modeling is growing and thank you to those of you who have contributed new labs. They are mostly in the form not entirely but many of them are in the form of Jupiter notebooks and they can now be launched either on binder of free service or on this new open Earthscape hub. And then webinars. And many of you know that we've been hosting a webinar series and thank you very much to the webinar presenters from the last year. If you missed a webinar. Don't despair because the webinars are recorded and posted online so if you go to the CSMS webinars portal, you'll find now over 40 recorded webinars on a whole variety of different topics so please check that out. I have to say that all of this would not be possible without both support from the National Science Foundation and a heck of a lot of work from a dedicated team in the integration facility so I want to give it a shout out to these folks. I also want to thank our graduate student volunteers who are helping out with this meeting. So all the folks pictured here are working hard behind the scenes to make this happen. So a couple of logistical notes. This is kind of a sketch of our program today. We have keynotes in the mornings, we'll have a breakout session after that today. Clinics in the afternoon so these are two hour blocks of time when you get to learn about some particular tool or technique or package or whatever. So posters in the afternoon, if you haven't already put up a poster. Go ahead and and find a spot there spots. I guess there's still at least one spot in this room and there's more around in the room over on the side here. Let's see clinics. If you've forgotten which clinics you signed up for just turn around your name badge and they should be listed here along with the room number in this building so this is big building as a guide in north that way. Yes, south that way. Floor one floor to floor three. Let's see we're going to have an award ceremony followed by a banquet banquet in quotes is going to be a relatively relaxed informal affair will be here in this building, the bank will be over in the cafeteria. So that should be good fun tomorrow. One other piece of it. And if anybody Lynn or anybody needs to remind me to say anything else going, going. Okay. Last thing I have to say about logistics is, unfortunately, in Boulder County, Colorado, the CDC has recently raised the level of community spread from green to yellow. So it means we need to be vigilant. If you need a test kit, we have some test kits on hand. We also have a supply of masks should you desire a mask. I plan to wear a mask when I'm not presenting or outside. We ask that if you do get a positive test while you're here, or experience serious symptoms, or informed of an exposure. If you would please let one of the meeting organizers know we won't share your name publicly but it helps us to keep a keep an eye on things and we can potentially help with the logistical consequences of getting a positive test. We're monitoring the CO2 level in this room so you know CO2 we're we're organisms we breathe out CO2 right so CO2 concentration in the air around us is a good indicator of ventilation quality. Right, everybody and everybody knows what it is outside around us right somebody want to tell me. This is good geopop quiz. We hit 420 parts per million. We're not in the place to see anymore. But anyway there's a meter out by the coffee coffee if you want to check that out. I last I looked at my portable meter it was in the 500 which is actually pretty good. So finally less since I don't want to end on kind of a bum note. Let me just share this one thought it's, you know, is this has been a rough time for a lot of humans on the planet right not just the pandemic. There's a lot of geopolitical upheaval. There's long anticipated climate upheaval that's unfolding before us. It's easy to get discouraged, but I think it's important to remember that people with training and experience and interest in earth and environmental science is broadly read. I think your skills and perspective are needed now more than ever. Actually, I mean there's the obvious reason that you all have the skill sets to help deal with a rapidly changing and evolving and dynamic environment. But also the perspective that you bring to the table of a perspective of deep time, a perspective of dynamically interacting physics chemistry and biology. And of course the habit as scientists of asking, as Bertrand Russell put it, what are the facts, and what is the truth that the facts bear out. That's a message the world needs today. Okay, so anyway, I'm looking forward to learning some really cool facts with you the next couple days. Any particular burning questions. I am now going to hand it over to Irina Overeem.
