Historical Data

Asean Water Portal

Historical Data

Historical data is key hydrological stations across different physiography and climate characteristics in the GM region. From long time-series of historical data we can identify normal conditions and detect trends towards new states, identify extreme values and the risk to be exposed to these, and evaluate the model performance against observations.

The portal provides data of all 1120 irregular sub-catchments in the GM that help users to understand character and natural variabilities of water resources so that both societal and environmental concerns can be planned accordingly. The time-periods often starts in 1980 to 2009.

The calculations are made on a daily time step and modelled data is given for a number of variables (such as Discharge (COUT-m3/s), specific discharge (SPEQ-mm/day), upstream corrected precipitation (UPCPRC-mm/day), upstream actual evaporation (upEVAP-mm/day), upstream potential evaporation (upEPOT-mm/day), local actual evaporation (EVAP-mm/day), local potential evaporation (EPOT-mm/day), local corrected precipitation (CPRC-mm/day), soil moisture root zone (SMRZ-mm/day), and air temperature (TEMP-o C).
