Here we present a meteorological dataset of the Rheraya catchment. It includes hourly meteorological observations from six automatic weather stations (AWS). These stations range from 1170 m to 3230 m and provide standard meteorological variables. They are stored in .dat file, i.e : StationName_met_data.dat. Inside each file the following elements are presents in every line : Year Month Day Hour Station_ID X Y Z Temperature Relative_Humidity Wind_Speed Wind_Direction Precipitation. We also provide snow height observations (Snow_depthOuka.txt). Each line correspond to a daily measured snow height recorded at Oukaimeden AWS (3200 m.a.s.l) from 1st November 2009 to 10 June 2009 by using an acoustic gauge. Additionally there is a shapefile containing GPS points collected during a 40 km long road trip. (trackkin.shp) Finally, we provide a time series of snow cover area maps derived from Formosat-2 images (8 m) and covering most of the catchment.
