COLUMN TITLES

Column 1: serial date (Matlab format): number of days since 00-JAN-0000
Column 2: date (Unix timestamp): number of seconds since 01-jan-1970
Column 3: incoming UV-A radiation [W.m-2]
Column 4: incoming UV-B radiation [W.m-2]
Column 5: air pressure [Pa]
Column 6: mean horizontal wind speed 2 m over roof of measurement cabin [m.s-1]
Column 7: unit vector mean wind direction 2 m over roof of measurement cabin [angular degrees]. All measured directions are weighted equally when calculating the mean.
Column 8: standard deviation of wind direction [m.s-1]
