DOI 10.12754/data-2023-0004 connected to AMT publication "Acquiring 
high-resolution wind measurements by modifying radiosonde sounding 
procedures". You find the following data in this repository:

	> balloon_filling:
	
		> balloon_filling.m:
		This  function calculates nozzle lifts required for both
		balloons for double balloon operations. 
		It is based on "Totex Balloon Burst Estimator" excel sheet.

		> RS_up_20220228_edt.txt:
		Standard "edt" data format created by the Vaisala MW41 
		sounding system for the standard configuration sounding on
		28 February 2022 from Kuehlungsborn, Germany.
		
		> RS_up_20220228_loc.txt:
		Radiosonde location file for the standard configuration 
		sounding on 28 February 2022 from Kuehlungsborn, Germany.
		
		> RS_updown_20220228_edt.txt:
		Standard "edt" data format created by the Vaisala MW41 
		sounding system for the improved configuration sounding on
		28 February 2022 from Kuehlungsborn, Germany.

			> BalloonCutter.zip:
			Zip archive containing the firnware running on the 
			microcontroller of our custom-made electronics that 
			operates both pyro cutters based on elapsed time 
			and/or pressure.
			
			> GUI:
				> BallonCutter_DelphiProject.zip:
				Delphi project for the application mentioned 
				below.
				> BCconfig.exe:
				Application to check the cutter prior to launch
				and set timers as well as pressure limits.
			
			> PCB_design:
				Folder containing KiCad schematics as well as 
				Eagle "board" file for the PCB as well as some 
				graphics files for easy accesss to the design.

		cap_fence.scad:
		OpenScad file for a "fence" that is 3D printed and glued
		onto the PCB arount the capacitors. This allows the 
		surroundings of the capacitors to be filled with epoxy
		resin in order to prevent damage due to low pressure.
		
		cap_fence.stl:
		Same as above but in stl format for 3D printing.
		
		fin_mount.scad:
		OpenScad file for the radiosonde mounting structure 
		as shown in the manuscript, Figure 7.
		
		fin_mount.stl:
		Same as above but in stl format for 3D printing.
		
		main_housing.scad:
		OpenScad file for housing of the electronics, as shown 
		in the manuscript, Figure 6.
		
		main_housing.stl:
		Same as above but in stl format for 3D printing.
