Hi Henrik,

Thanks! Do you have an instrument name for the aerosol lidar, by chance? That is probably the instrument of greatest interest for flight planning, because it could tell us about whether an aerosol layer of interest is present, the strength and altitude of the layer, and something about the aerosol type (depending on the kind of lidar). Thanos please provide the info about this.

Other things that would be helpful for flight planning:

  *   Your impressions of aerosol conditions and sources from the ground
During summer most aerosols are ultrafine, when the coast is ice free (not happening every year) we have frequent episodes of fog, ozone is at is general minimum around 20 ppbv.

  *   Interesting surface spikes (or lack thereof) of CCN, INP, and aerosols of different types based on black carbon, DMS, aerosol size, etc.
I include the links to two papers on INP from the station (https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdoi.org%2F10.5194%2Facp-19-5293-2019&data=05%7C02%7CArcsix%40espo.nasa.gov%7C437c90ef405e47d4207c08dc89244508%7C7005d45845be48ae8140d43da96dd17b%7C0%7C0%7C638536039139826142%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C60000%7C%7C%7C&sdata=XIO6fOEalZ16dN%2FDF4nltJPxgpgFlrFsLWCo9%2B4B56Y%3D&reserved=0.    https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdoi.org%2F10.5194%2Facp-23-4741-2023&data=05%7C02%7CArcsix%40espo.nasa.gov%7C437c90ef405e47d4207c08dc89244508%7C7005d45845be48ae8140d43da96dd17b%7C0%7C0%7C638536039142639216%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C60000%7C%7C%7C&sdata=IhKraiftnWRRSo%2BFrtFyx%2Bq5g3BD%2BuWfFSlRGf2%2B1z4%3D&reserved=0)  as well as one on hygroscopicity https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdoi.org%2F10.5194%2Facp-2022-413&data=05%7C02%7CArcsix%40espo.nasa.gov%7C437c90ef405e47d4207c08dc89244508%7C7005d45845be48ae8140d43da96dd17b%7C0%7C0%7C638536039142639216%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C60000%7C%7C%7C&sdata=YD1%2Fd5D%2BGCiNSxDWwSNaeoXLEk4%2Fkht4ip%2F25cg9VDo%3D&reserved=0. TROPOS is operating a CCN counter but they are busy to look into data right now

  *   Black carbon at the surface will also help us evaluate whether the models we are using for forecasting are accurate.
BC is very low. For example the wild fires in Canada last year could not be observed at ground level. We have not yet looked how it affects our long term ceilometer and windcube data.
I know that is a lot! Would that be manageable for you all?  Like I said, for flight planning, perhaps the most relevant info would be the lidar data. Would you be able to transmit an image of those data?
The ceilometer (CL51) and windcube are from Vaisala.

ARCSIX folks, did I miss any key parameter? The data they are collecting to my knowledge are listed here:

Hi again

Apparently the last words disappeared I try again and then I also specify the instrument operated by EPFL
/Henrik

Dear Ralph and Sebastian

You are in the middle of your first part of the ARCSIX campaign but we are already planning our summer campaign. We plan to start the 17th July and end 12th august. We will operate our normal monitoring activities including ceilometer and windcube. During the campaign, EPFL is operating an aerosols LIDAR and we will add a PTR-TOF-MS and HTDMA. The monitoring activities are listed in the presentation I gave at the meeting at NASA.

We hope to have a starlink connection. If so it will be rather easy to send data to you on a daily basis. Please send a list of parameters that will be of your interest.

Cheers

Henrik
