The adjacency information readily available in the grid structure is very useful for many applications and particularly grid-based interpolation.
Locating the nearest precipitation monitoring station to a site of interest often proves challenging. Becher, A et al (2013): A description of the global land-surface precipitation data products of the Global Precipitation Climatology Centre with sample applications including centennial (trend) analysis from 1901–present.
Global Precipitation Climatology Centre (GPCC), DWD, Internet Publikation, 1-12. Each file provides monthly values in a 5x5 lat/lon grid for the Continental United States.

Canadian Gridded Temperature and Precipitation Anomalies (CANGRD) CANGRD is a set of Canadian gridded annual, seasonal, and monthly temperature and precipitation anomalies, which were interpolated from stations in the Adjusted and Homogenized Canadian Climate Data (AHCCD); it is used to produce the Climate Trends and Variations Bulletin (CTVB).
Obtaining a long-term precipitation data time-series can be a difficult and time-consuming process. The data may be from radar sources or could be the result of complex calculations exterior to the program. The resulting product is a spatially and temporally complete, high-resolution (1/24th degree ~4-km) gridded dataset of surface meteorological variables. The precipitation data are quality-controlled, multi-sensor (radar and rain gauge) precipitation estimates obtained from National Weather Service (NWS) River Forecast Centers (RFCs) and mosaicked by National Centers for Environmental Prediction (NCEP). A grid is not just a set of points that meet certain geometric properties. E-OBS gridded dataset. Rather, a gridded data set relies on an ordered relationship among the points in the grid. Earth Syst. GHCN V2 contains gridded precipitation anomalies calculated from the GHCN version 2 … Regardless, the grid data must be stored as a precipitation grid.
This is the download page for the ENSEMBLES daily gridded observational dataset for precipitation, temperature and sea level pressure in Europe called E-OBS. Precipitation Data Retrieval from a Gridded Database. Subash Yeggina, Ramesh S. V. Teegavarapu, Sekhar Muddu, Evaluation and bias corrections of gridded precipitation data for hydrologic modelling support in Kabini River basin, India, Theoretical and Applied Climatology, 10.1007/s00704-020-03175-7, (2020). gridMET blends spatial attributes of gridded climate data from PRISM with desirable temporal attributes (and additional variables) from regional reanalysis using climatically aided interpolation.
Both GPCC and WM underestimated seasonal precipitation, especially for spring precipitation. Spanning 50°S-50°N (and all longitudes), starting in 1981 to near-present, CHIRPS incorporates 0.05° resolution satellite imagery with in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring. Global Precipitation Climatology Centre (GPCC), DWD, Internet publication, 1-8 Rudolf, B., U. Schneider (2005): Calculation of Gridded Precipitation Data for the Global Land-Surface using in-situ Gauge Observations, Proceedings of the 2nd Workshop of the International Precipitation Working Group IPWG, Monterey October 2004, EUMETSAT, ISBN 92-9110-070-6, ISSN 1727-432X, 231-247. Table of TRMM data downloads and documentation. Among the three gridded data sets, GPCC had the highest correlation and lowest bias compared with CRU and WM when against the OBS.

Evaluation of Gridded Precipitation Data and Interpolation Methods for Forest Fire Danger Rating in Alberta, Canada. Gridded precipitation data must be stored as a precipitation grid before it can be used in the meteorologic model. These missions study rainfall and other types precipitation around the globe. Based on mass balance calculations and Turc-Budyko analysis, this study investigates the accuracy of thirteen widely used precipitation gridded datasets for sub-basins in the Upper Indus Basin (UIB) in the Himalayas-Karakoram-Hindukush (HKH) region.
MATLAB uses a similar idea for creating data grids. Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) is a 30+ year quasi-global rainfall dataset. The official website for NASA Precipitation Measurement Missions. Accurate precipitation data are vital for hydro-climatic modelling and water resources assessments. The Gridded 5km GHCN-Daily Temperature and Precipitation Dataset (nClimGrid) consists of four climate variables derived from the GHCN-D dataset: maximum temperature, minimum temperature, average temperature and precipitation.
