 I think here is one Henry P&O, I'm not sure, oh yeah, he's here. Is my turn? Okay. I'm trying to share, I'm not, can you confirm that this, my thing is... Share screen button green in the center, down. Yeah. Yeah, just exactly in the center of the bottom, near the chat. Yes, let me check, please, where, what is this? It has this, okay here, it was covered by another, yeah. Okay, share, let me start my time counter. Yes. Okay. Please confirm that it's now showing my screen. So first of all, let me send to the organizers for, let me get into this event. The main purpose was just to get a basics and understanding of letters, just to look for next research topics because I came from the radio field, radio frequency field. I will share later my, quickly my research on polar mesosphere, but the best goal is to attend, estimate the ice particles distribution inside the PMSE layer. I will describe what is PMSE later, and also to estimate if possible the temperature profile also inside the PMSE layer. Now in Peru, I involve also in renewable energy, I have to adapt because here space physics is not, it's only one place to do that. And I'm now living in my hometown, so here is how to apply many things I have learned before now to renewable energies and the first thing is just estimate or just to evaluate the feasibility to develop a basic LiDAR to estimate wind velocities. The need for LiDAR is because radars is a little more complicated to get the measurements at short distances. And now also I involve in an aquaculture project, therefore I was interested on the beach LiDAR, but in this case, the idea that I joined this group to develop is to use these LiDARs that are not available in the market that can get this volume. So the purpose of the fish farms are just to estimate the volume of the fish. So because I'm not an LiDAR expert and even an amateur, I just look for solutions on the market to estimate the volumes of the layer. So to do all these, let me share quickly my former expertise, it was on radiofrequency applied to study the ionosphere, specifically to study the polar mesosphere. In the polar mesosphere, well, before continuing, all my research couldn't be done without the collaboration with all my partners. And of course, without the support of the Artic University of Norway, also I couldn't do this. First of all, let me share quickly the instruments that I was using there, where is located in the city of Tronsø. There is a place for the ICAD, the ICAD is a European Scientific Association for Inconquering Scattered Radars. And there we have these sets of radars in this place, a very nice place, also there are also optical instrumentation, especially from Japan. Now they keep some LiDARs there also, but my field was on radar. All the radars that I use it, all those are market colors, the HF radar, the VHF in 56, 933 and 224 frequency. The medium that we observe and study looks like this when it's observed by the satellite from the AIM project. These are the mesospheric clouds. And this is a view from the top of the planet, from the north pole. So these are the sketch of how we proceed. We have all these radars and the heating facility. I forgot to describe the heating facility. It's a facility that transmits a very powerful wave that is that much the frequency of the plasma, the resonance frequency of the plasma, so the electrons agitate. And when the electrons excite, then they like disconnect from the structures and the radar echo decrease. So we use this change, this effect of the heating on the medium and on these polar mesosphere clouds to evaluate what are the sizes of the dust particles. I will describe who are involved in this PMC. First of all, the dust particle from meteor stars. As we know the meteors arrive very quickly from charged particles, neural dynamics, and also there are very low temperatures. Therefore, I was interested on the talk from Joseph about the measuring ice, because these layers are a lot of ice there. And then we have to study in that sense. And also charged particles and so on. So we were studying this and I have a lot of measurements together with my group to study this overshoot effect. So basically that was this is the all the research that was doing before just quickly just show that I know that time is over some research that we have done. This year we call this one one paper I just restarted this research that was kind of parentheses on the world and this is my current topic so aspect sensitivity. So let's, let's keep just anybody wants to talk more about this as you also mentioned by email, but it is all for now. Yes, thanks. Don't worry to turn off your timer. Okay, thanks. Thanks a lot. Time is over. Yeah. Yeah, just, just keeps going. Anybody got a question. Good. Thank you very much. Thank you very much. I recommend that you probably include less images because it's just a lot of information to absorb in five minutes. I think this is, this is really great stuff. This is what some of the research people are doing at my lab. You can try to look at the cross cross polarizing your, your detector, because from that you can also get the shape of that matters and I think generally right now, people are looking for the thermodynamic effects of these ice on the field, you know, and if it can cause some very serious thermodynamic effects that we're not sure about. And also, I didn't exactly know what you meant by PMSE. I don't think you explained it. Sorry, it's something that the time is the sound is distracting with you. Yes. If possible, please. Let me get your contact because now all this stuff has been done in radars and radars with both the kind of limitation to estimate the particles, especially because we attempt to estimate the sizes that are the nanometer sizes so LiDARs can also be useful. I didn't get into this just get curious about the LiDARs because of these applications that I want to apply here in Peru. As I mentioned before, with LiDAR also with this, especially this project because I think it's feasible with these devices that are available in the market. I think probably we can get some results just using these devices, but of course I'm blind on the LiDAR so therefore I wanted to know more on this. I get some basics during the master degree because it also includes these topics but didn't apply for research until now. So I would appreciate a lot is someone also is interested to collaborate. I just joined this project so therefore everything is just starting. Okay, you got a question come from Joe Shaw. Okay, so a comment and a question. So for the aquaculture project. My concern is that the LiDAR that you showed has a near infrared wavelength, and that won't work in the water. That wavelength does not penetrate water at all. So, I mean maybe one millimeter. That's why my lab is building new kinds of LiDARs at wavelengths that will penetrate the water because most LiDARs, especially these kinds of small commercial systems, they all use infrared diode lasers and it won't work. So you need something in the green or blue. Thank you very much because I was looking for solutions and I bought those. My filter now is a price because I found some LiDARs that are very expensive. So those cheapest are those because you can see now but I appreciate your feedback because you most probably will allow me to don't lose time on this. Yeah. And then my quick comment is that the fish also we will make them to pass over a camera or a chamber where in this chamber we can take these measurements not on the not on the farm. It's 12 hours. So, so that maybe could help something I don't know, but I appreciate you. Thank you. Yeah, that's an interesting. If you want to know more about LiDAR being used for polar clouds. I suggest you look up my colleague Richard Collins. See you. Oh, CLIL is Richard Collins University of Alaska. Oh yeah, I think I probably I met him. It's a tall guy right. Yep. Probably. Yes. Probably you have heard also about many weather, perhaps. What was that many weather. But okay, I will keep the Richard Collins on on on the suggestion. Okay. Okay. Great day any more questions. Okay. Thanks, Henry. Thanks a lot. Now, now I understand the questions you're asking during Joe's talks.
