SAFARI 2000 Daily Global Precipitation Estimates, 1999-2001

January 1979 through the present is the temporal coverage of the GPCP Version 2 Combined Precipitation Data Set, from which this subset is derived. This dataset provides daily, 1-degree gridded global precipitation estimates for 1999-2001, created by the GPCP Merge Development Centre at NASA Goddard. It merges satellite infrared brightness temperature data with gauge measurements to produce a long-record, observation-only analysis.

Use Cases

• Analyzing daily precipitation variability over southern Africa during the SAFARI 2000 field campaign using the 1-degree gridded data.
• Validating climate model precipitation outputs against a merged satellite-gauge observational product.
• Studying the relationship between infrared brightness temperature histograms and precipitation estimates on a global grid.
• Investigating interannual precipitation changes from 1999 to 2001 using a consistent, blended data source.

Strengths

• Provides a long-record estimate starting in January 1979, offering over 40 years of potential context for the 1999-2001 subset.
• Merges multiple data sources (satellite IR and gauge measurements) to leverage the strengths of each observation type.
• Offers global coverage on a consistent 1-degree by 1-degree spatial grid.

Limitations

• Specific row count, file size, and detailed column names are not provided by any source.
• Conflicting last updated dates exist: one platform shows 2026-03 12, while another shows 2001-12-31, indicating potential metadata inconsistency.
