Weather dataset from Otemma glacier forefield, Switzerland (from 14 July 2019 to 18 November 2021)

Weather data collected in the Otemma forefield (Switzerland) from 14 July 2019 to 18 November 2021. Data were collected by the research teams of Bettina Schaefli2 and Stuart N. Lane1. 1 Institute of Earth Surface Dynamics (IDYST), University of Lausanne, 1015 Lausanne, Switzerland 2 Institute of Geography (GIUB), University of Bern, 3012 Bern, Switzerland For further information, please contact: [e-mail] [e-mail] Description of data : WeatherData.csv Time span of data : 14 July 2019 to 18 November 2021 Time step : homogenized 10 minutes-averaged data Location of data (Coordinate in SWISS LV95 (EPSG:2056) - Glacier snout Station : 2598615 / 1087375 - Glacier center Station : 2600495 / 1088631 - Floodplain Station : 2598096 / 1087087 STRUCTURE OF DATA : tidy dataframe with following headers : - date : local date (UTC+01 with daylight saving time) - variable : parameter of interest, with following classes : Air_humidity : Air humidity in percent of air saturation [%] Air_temperature : Air temperature in [°C] Atm_pressure : Atmospheric pressure in [hPa] Incoming_radiation : Incoming shortwave radiation in [W/m2] Precipitation : Liquid precipitation measured [mm] - name : location of data (see coordinates above) - dateUTC : date with UTC timezone Device used for data acquisition : - Air_humidity/Air_temperature/Atm_pressure : Decagon VP-4 - Incoming_radiation : Apogee Instruments SP-11 - Precipitation : Double tipping buckets rain gauge from Davis Instruments (resolution 0.2 mm) Description of data : RainComposite_Otemma_Arolla.csv Time span of data : 01 July 2019 to 18 November 2021 Time step : homogenized 10 minutes-averaged data The dataset compiles the measured rain during summer at the closest weather station (Glacier snout). For the winter period (and few gaps during the summer), the solid precipitations (snow) from the closest MeteoSwiss weather stations (SwissMetNet) were used. Gaps where filled with 1) MeteoSwiss Otemma and if data were still missing filled with 2) MeteoSwiss Arolla Location of data (Coordinate in SWISS LV95 (EPSG:2056) - Glacier snout Station : 2598615 / 1087375 - Otemma camp Station : 2597508 / 1086653 - MeteoSwiss Station : 2596476 / 1085864 - MeteoSwiss Arolla : 2603507 / 1095832 STRUCTURE OF DATA : tidy dataframe with following headers : - date : local date (UTC+01 with dst) - variable : parameter of interest Precipitation : Liquid and solid precipitation [mm]. Composite dataset composed of melted snow (snow Water Equivalent, in mm, from MeteoSwiss station) and Rain (in mm from Glacier station). - Location : location of data (see above) - dateUTC : date in UTC timezone Device used for data acquisition : - Glacier snout Station : Double tipping buckets rain gauge from Davis Instruments (resolution 0.2 mm) - Otemma camp Station : Double tipping buckets rain gauge, Spectrum WatchDog 1120 (resolution 0.25 mm) - MeteoSwiss : see SwissMetNet project Description of data : Otemma_weather_Plot_alldata.html An interactive plot generated with python plotly (open in web browser) containing all above described data.
