Precipitation Reconstruction Land (PREC/L): 1948-present

Precipitation Reconstruction Land (PREC/L): 1948-present

Precipitation gauge measurements over land from the GHCN-v2 (Global Historical Climatology Network version 2) are interpolated onto 3 grids: at 0.5, 1 and 2.5 degree resolutions via optimal interpolation. Note: As of May, 2011 the GHCN version 3 station data set is available.

Key Strengths

Land grid points are derived from high quality station gauge measurements.

Near real-time updates

Key Limitations

Smaller gauge network than GPCC; no new stations added since GHCNv2 release ~1997
