Snow Dataset For The Rheraya Catchment (Morocco) (2008-2009)

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 : <em>Year Month Day Hour Station_ID X Y Z Temperature Relative_Humidity Wind_Speed Wind_Direction Precipitation.</em> 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. These file are in Geotiff format and given by, : YearMonthDay.tiff本文提供一套针对Rheraya流域的气象数据集。该数据集包含6个自动气象站（Automatic Weather Station, AWS）的逐小时气象观测数据，这些气象站的海拔覆盖范围为1170米至3230米，观测项目涵盖标准气象要素。数据以.dat格式存储，命名格式为StationName_met_data.dat。每个文件的每一行均包含以下要素：年、月、日、时、站点ID、X坐标、Y坐标、海拔高度、气温、相对湿度、风速、风向、降水量。 本数据集同时提供雪深观测数据，存储于Snow_depthOuka.txt文件中。该文件的每一行对应Oukaimeden自动气象站（海拔3200米）于2009年11月1日至2009年6月10日期间，通过声学测雪仪获取的逐日雪深观测值。此外，数据集还包含一份形状文件（shapefile，文件名为trackkin.shp），其中存储了一次40公里公路行程中采集的GPS点位数据。 最后，本数据集提供一套基于福卫二号（Formosat-2）8米分辨率影像生成的积雪覆盖面积时间序列图，覆盖流域绝大部分区域。该类数据采用GeoTIFF格式存储，命名格式为YearMonthDay.tiff。
