Climate trajectory & ENSO

Three layers on one page: charted CMIP6 daily projections (EC_Earth3P_HR, MPI_ESM1_2_XR, CMCC_CM2_VHR4), the ENSO watch (current El Niño/La Niña phase plus nine NOAA PSL indices), and the observed monthly record at the pinned point from PSL gridded datasets (GPCP, PREC/L, GPCC precipitation; OLR convection).

How to use it

1. Open /app/climate.
2. Enter a coordinate (the default points to the Manaus area in the Amazon).
3. Pick a start and end date between 1950-01-01 and 2050-12-31 and submit — yearly temperature and precipitation charts plus min/mean/max per model.
4. In ENSO watch, pick an index (ONI, Niño 3.4, SOI, MEI v2, …) — a diverging bar chart of the window plus the current phase classification.
5. In Observed record, pick a gridded dataset — the monthly series at the pinned point, charted.

Limits & caveats

• This is a quick aggregate — for parcel risk scoring we ensemble more models and bias-correct against ERA5 (Phase 5).
• Open-Meteo limits range to 1950–2050 daily resolution.
• ENSO phase is classified from the latest ONI value; a full episode needs 5 consecutive overlapping seasons (reported as episode_established).
• The interpolated OLR series ends 2022-12 (AVHRR product discontinued); gauge datasets are land-only — ocean cells return null.
