Geostatistical interpolation of daily rainfall at catchment scale: the use of several variogram models in the Ourthe and Ambleve catchments, Belgium. Analyses of observed and anticipated changes in extreme climate events in the northwest Himalaya. Singh D., Jain S., Gupta R., Kumar S., Rai S., Jain N. Progress in research on homogenization of climate data. Development of high spatial resolution rainfall data for Ghana. Rainfall summaries by climate division (tables & maps) - Last 30 Days N. SPAS is a gridded rainfall analysis software package that combines all available rainfall data, including rain gauge (subhourly, hourly, and daily). Validation is done using 19 Ghana Meteorological Agency (GMet) gauge stations (10%) by comparing the ratios, correlations and Root Mean Square Error (RMSE) of the observed to the gridded for the seasons.ĭaily rainfall Ghana Gridding High resolution Interpolation Minimum surface curvature Point-pixel.Īryee J.N.A., Amekudzi L.K., Quansah E., Klutse N.A.B., Atiah W.A., Yorke C. This data cures such deficiency by generating a high resolution (0.25° × 0.25°) gridded daily rainfall using the Minimum Surface Curvature (MSC) interpolation for 190 stations distributed across all agro-climatic zones of Ghana. However, the sparse and limited distribution data from gauge measurements, coupled with periods of no record of daily rainfall data, limit their application for any meaningful endeavour. This is particularly so with agricultural output determination in much of Africa with Ghana not exemption, where data is required for intra and inter-seasonal assessment of the impact of rainfall on yield. Rainfall data is necessary at resolutions that allow modelling of environmental change and its impact on socio-economic well-being.
