TEAMx sEOP 2025; IVTA (Flintsbach, Germany); Radiosoundings and drone measurements during 2 IOPs (IOP18: 18/19 July; IOPDWD: 12/13 August)

This dataset contains data from radiosoundings and drone ascents during two IOPs conducted during the TEAMx sEOP 2025 in the Inn Valley Target Area (IVTA). More details about TEAMx can be found at http://www.teamx-programme.org.The first IOP corresponds to IOP18, the second IOP was conducted after the sEOP and was therefore named IOPDWD. DATA SET DESCRIPTION 1. Measurement location and measured variables Radiosonde launches and drone measurements were conducted at the site of Brannenburg (456m MSL) at the following coordinates: Coordinates Instrument Measured Variables Radiosonde 47.72851N 12.12714E Radiosonde Vaisala RS41 GPH, WDIR, WSPEED, T, DT, potT, P Drone 47.72854N 12.12724E Drone DJI Mavic pro, iMETXQ2 T, RH, P Variables: T=temperature [K], DT= dewpoint temperature [K], potT= potential temperature [K], RH=relative humidity [%], P=pressure [hPa], WDIR=wind direction [°], WSPEED=wind speed [m/s], GPH=geopotential height [gpm], Drone ascents were conducted up to an altitude of ~120m MSL Data is available for the two IOPs listed in the table below.

Data corrections No corrections were applied to the data. 3. Data file structure The data are provided as tab separated .txt files in two folders: · RASO: contains one file for each radiosonde launch in the format RASO_yyyymmddHHMMSS.txt. with the following wildcard characters: yyyy - year; mm - month, dd - day; HH - hour, MM - minute, `SS` - second The first three columns contain the time since launch in seconds, the longitude displacement (lond in degrees) and the latitude displacement (latd in degrees). Further columns correspond to the parameters as listed in section 1. · DRO: contains one tab separated .txt file for each drone ascent in the format DRO_yyyymmddHHMMSS.txt. The first four columns contain the time in UTC, longitude (lon in degrees), latitude (lat in degrees) and elevation (elev in meters above ground). Columns 5-7 correspond to the parameters as listed in section 1. The last column contains the number of satellites. 4.
