Precipitation intercomparison — landing page site

Global, land-only, monthly comparison of CHIRPS v2/v3 (with and without stations), IMERG Final and Late, ERA5, the JRC ASAP blend and six gauge analyses on a common 0.5° grid: relative bias, anomaly agreement, triple collocation, dry-tercile agreement and trends, all split by GPCC gauge coverage. Headlines: two-thirds of 50°S–50°N land never had a GPCC gauge in 2001–2020; mean biases are small and the wet end is consistent with gauge undercatch; in gauge-free cells products agree on only ~two-thirds of each other's dry 3-month terciles; ERA5 dries in Africa and arid climates (−5%/decade vs GPCC, −3% vs gauge-free CHIRP v3); CHIRP/CHIRPS v3 have a meridional seam near 72°E in Central/South Asia; IMERG Late has drifted ~6% wetter than Final since 2022 and the team archive holds NASA's corrupted 17 Oct–2 Nov 2024 values.

Drought AA indicators site

Cross-country backtest (2001-2024) of temperature, rainfall, water-balance and vegetation indicators against six drought-impact ground truths (FAOSTAT staple production, CERF/EM-DAT drought seasons, framework-documented bad years, FEWS NET official subnational yields nationally and in framework areas, GDHY gridded yields) across the ten OCHA drought-AA countries. Primary output is one pooled matrix (LOO/LOYO R² for continuous targets, within-country AUC for binary). Detrended growing-season temperature and FAO ASI/VHI lead on production shortfalls (LOO R² 0.13-0.15 vs 0.02 for the ASAP biomass anomaly Burkina Faso's observational trigger keys on); rainfall/SPI-3 lead on the binary records (AUC 0.62-0.64 impact seasons, 0.76-0.78 bad years); within provinces no indicator exceeds LOYO R² 0.04. Recommends adding temperature to every observational-window candidate set alongside ASI/VHI and a rainfall arm.

External AA frameworks review site dashboard

Independent review of the WFP/FAO Southern Africa drought AA triggers proposed for the CERF El Niño 2026/27 harmonisation: recovers the activation records behind the agencies' stated return periods from public endpoints (PRISM operational trigger CSVs, IRI fbfmaproom2 hindcast API), computes Weibull RPs and trend-split RPs, cross-checks triggers and 2026/27 forecasts against ERA5/SEAS5 (detrended, from the team rasterstats DB), and publishes a password-protected review site.

Not built by the team: partner-operated tools and published documents that our frameworks and analyses rely on — IRI maprooms, national services' dashboards, framework documents — linked from the knowledge base.

How this page stays current. It is generated, not maintained. GitHub Pages sites are swept from the ocha-dap org and probed daily (gen_pages_registry.py); Azure web apps come from the daily infrastructure baseline; titles, blurbs, hazards and countries come from each surface's page in the knowledge base; thumbnails are captured weekly. Sources: registry 2026-11-15 06:56 UTC · Azure estate 2026-11-14 12:45 UTC · 68 of 180 live pages have a thumbnail · page built 2026-11-15 07:15 UTC.

External resources are links the knowledge base relies on but the team did not build — a partner's maproom, a national service's dashboard, a published framework document. They sit in their own section, out of the counts above: a surface declared origin: external, or one on any host outside the team's publishing platforms (GitHub Pages, Azure, Netlify, Quarto Pub, shinyapps).
