*Satellite Weather Data sources:
Global Satellite Mapping of Precipitation (GSMaP), precipitation (band: hourlyPrecipRateGC) - Details are provided at http://www.gportal.jaxa.jp/
Climate Hazards center InfraRed Precipitation with Station data, precipitation (band: precipitation ) (CHIRPS) - Details are provided at https://www.chc.ucsb.edu/data/chirps

A web platform was developed for an automatic point scale daily data acquisition process and to be made available for interested parties in open access, as it does not require any knowledge of remote sensing data acquisition and processing. The web platform requires the user to enter a time period and the desired coordinates. The coordinates can be inserted by entering them manually or by clicking the area of interest on the map. The web platform produces the daily GSMaP precipitation data from the original hourly data, daily GLDAS maximum temperature (Tmax) and minimum temperature (Tmin) data from the original 3-hourly data, and CHIRPS data originally in daily scale. The GLDAS air temperature data are originally in Kelvin units which were converted to Celsius.
This tool has been developed for scientific purposes within the project "KlimALEZ – Increasing climate resilience via agricultural insurance – Innovation transfer for sustainable rural development in Central Asia" implemented by Leibniz Institute of Agricultural Development in Transition Economies (IAMO) and funded by German Federal Ministry of Education and Research (BMBF), Germany.
