NOAA GOES-19 ABI 2 km Full-Disk Level 2 Products

GribStream Code: goes19abi

Current coverage: five NOAA Level 2 full-disk product families begin April 8, 2025. The four FDCF fire fields begin July 10, 2026; earlier FDCF scans are not currently included. These are observation-derived analyses, not forecasts; forecasted_at and forecasted_time identify the same scan and horizon is 0.

Stable GOES-East record: coverage begins with the first full UTC day after GOES-19 entered operational service in the GOES-East slot. Earlier checkout and orbital-drift data are excluded so this dataset uses the operational fixed grid centered at 75W.

Availability and open data: new observations depend on NOAA's satellite feed, so maneuvers, calibration, outages, and product transitions can create gaps. NOAA data distributed through its Open Data program are available for public use; attribution is requested and NOAA endorsement must not be implied.

Description

ABI, the Advanced Baseline Imager, observes the GOES-East disk in 16 spectral bands. The cloud and moisture imagery fields combine those calibrated channels into a consistent full-disk view, from visible reflectance through water-vapor and infrared brightness temperatures.

The derived Level 2 fields turn those radiances into application-focused observations: fire detections and radiative power, aerosol optical depth, downward shortwave radiation, quantitative precipitation estimates, and sea-surface temperature. Together they connect storm, smoke, energy, hydrology, and ocean-monitoring workflows in one fixed-grid dataset.

Each retrieval has limits. Several products depend on daylight, clear-sky conditions, cloud screening, or assumptions about atmospheric and surface properties. Viewing geometry and footprint size degrade toward the limb. Fire detections are not a substitute for incident confirmation, and temperature or aerosol retrievals can be absent under clouds or outside their valid domain.

Use /api/v2/goes19abi/timeseries for point histories and /api/v2/goes19abi/runs for exact scan times or gridded extraction. The generated inventory below lists all 24 selectors and their source units.

Detail

• Archive begins: 2025-04-08
• Official NOAA GOES-R Level 2 product guide: https://goes-r.noaa.gov/products/docs/PUG-L2%2B-vol5.pdf
• Key features:
  • Sixteen CMI_C01-CMI_C16 cloud and moisture imagery bands, with reflectance for bands 1-6 and brightness temperature in K for bands 7-16.
  • Fire characterization fields Mask, Power, Temp, and Area, plus AOD, DSR, RRQPE, and SST.
  • One source-native 5,424 by 5,424 GOES-East fixed grid, corresponding to about 2 km sampling at nadir.
  • Twenty-four exact selectors, preserving NOAA field names and units; most products update about every 10 minutes, while sea-surface temperature is hourly.
• Resolution: One native geostationary fixed grid with 5,424 by 5,424 cells at about 2 km sampling at nadir. Ground footprints become larger toward the limb, and cells outside the visible Earth disk are null.
• Temporal coverage: Full-disk imagery, fire, aerosol, radiation, and rainfall products are generally published at approximately 10-minute intervals. Sea-surface temperature is hourly. Exact source scan times include seconds.
• Primary uses: Cloud and moisture monitoring, tropical-cyclone and convection analysis, wildfire detection and fire radiative power, aerosol and smoke context, surface solar-resource monitoring, satellite rainfall estimation, and ocean temperature tracking.
