LIAISE_ELS-PLANS_UKMO_MTO-10MIN_L2

This dataset contains  

Vertical characteristics: 

Air temperature at 1.2m, 10m, 25m, 50m.   

Relative humidity at 1.2m, 10m, 25m, 50m. 

Absolute humidity at 2m, 10m (these ae uncalibrated measurements from the Licor and Krypton, respectively, and were used in calculating humidity fluxes only. Please use relative humidity and air temperature to calculate absolute humidity if required.)  

Wind speed, direction, gust strength and turbulence derived characteristics at 2m, 10m, 25m, 50m (measured with both north and south facing sonic anemometers.) 

Visibility at 2m,. 

Pressure at 2m. 

Upwards and downwards shortwave and longwave radiation at 2m 

Surface measurements: 

Tipping bucket rainfall. 

Infra-red surface temperatures taken at 2m (measured with both north and south facing thermometers.) 

Grass canopy temperature and relative humidity at 2 locations with slightly different characteristics and to ensure observation resilience. 

Subsurface characteristics: 

Soil temperatures at 1 cm, 4 cm, 10cm, 17cm, 35cm. 

Soil moisture at 2cm, 10cm, 20cm, 30cm, 40cm

Soil heat flux taken at 2cm at 2 locations to examine heterogeneity and ensure observation resilience. 

The data is column oriented with quality flags preceding the data column.   

Quality flags: | = data OK, X = data flagged as bad, dummy value of 1x1011 applied, m = data missing, ? = possibly suspect data, do not use for bulk processing/statistics, c = calibration suspect, D = sonic orientation bad for wind direction – applied to data derived from sonic anemometers only and indicates that the wind and turbulence data for those times in particular may not be reliable.
