ACIS (NOAA Regional Climate Centers)

Observed weather history for a piece of ground in the contiguous United States from the Applied Climate Information System: PRISM gridded daily and monthly precipitation, temperature and growing degree days for a GeoJSON point or polygon, nearby observing stations and their daily records, and county / climate-division / basin / forecast-office lookups. Anonymous public data API; every result carries spatial_precision, sources, missing layers and a location echo.

1Request
objectRequired

GeoJSON (RFC 7946, WGS84, positions as [longitude, latitude]): a Point, Polygon, MultiPolygon, or a Feature wrapping one. Rings must be closed; altitude is ignored; a FeatureCollection is refused (send one place per call); geometries crossing the antimeridian are refused. Structural problems are reported as invalid_input with a JSON pointer and a stable code (ring_not_closed, ring_too_short, latitude, longitude, antimeridian, too_many_vertices, too_large, outside_coverage).

string

Defaults to yesterday (UTC); PRISM revises the most recent ~6 months and never has the current day.

number

Growing-degree-day base temperature in Fahrenheit (ACIS computes GDD in F); default 50.

boolean

Set false to return only the summary, cells and provenance.

string

Defaults to 30 days before `end`.

Ready-made Firecrawl tools that call ACIS (NOAA Regional Climate Centers).

Uses ACIS (NOAA Regional Climate Centers), National Weather Service API (api.weather.gov), NASA POWERAlmond pollination hive move timingUse when a commercial beekeeper is deciding when to truck hives into almond orchards for pollination. Reads growing degree days and temperatures at the orchards, frost and storm alerts, the hourly forecast for bee flight conditions and the month's normals, then picks a delivery window.4 toolsOpen
Uses ACIS (NOAA Regional Climate Centers), National Weather Service API (api.weather.gov), NASA POWERInsect pest spray timing by degree daysUse when an independent crop consultant is timing scouting and insecticide applications for a degree-day driven pest. Reads accumulated growing degree days from the biofix date at the base the extension model uses, projects the next week from the forecast, and checks wind and rain for spray windows, then schedules visits.4 toolsOpen
Uses ACIS (NOAA Regional Climate Centers), NASA POWER, National Weather Service API (api.weather.gov)Planting window go or waitUse when a farmer, agronomist or custom planter must decide in spring whether to plant a field this week or wait. Reads recent rainfall and growing degree days at the field, root-zone soil moisture, the seven-day forecast and any active alerts, and gives a go, wait or partial-go call with the numbers that drive it.7 toolsOpen
Uses ACIS (NOAA Regional Climate Centers), Element 84 Earth Search (Sentinel-2 L2A), USFS Wildfire Risk to Communities, National Weather Service API (api.weather.gov)Vineyard harvest timing and smoke riskUse when, late in the season, a winemaker, vineyard manager or grape buyer must time harvest around ripeness and wildfire smoke risk. Tracks season-to-date heat against normal, reads canopy vigour by block from satellite, checks wildfire risk and active fire-weather alerts, and turns them into a pick-order plan.7 toolsOpen
Uses National Weather Service API (api.weather.gov), ACIS (NOAA Regional Climate Centers), NASA POWER, Element 84 Earth Search (Sentinel-2 L2A)Crop hail claim weather verificationUse when a crop insurance adjuster needs to verify a hail or windstorm claim before a field inspection. Reads severe weather warnings issued over the field around the reported date, station-grid rainfall and temperatures, and satellite vegetation indices before and after the event, then states whether the record supports the claim.5 toolsOpen
Uses NOAA National Hurricane Center (nhc.noaa.gov), ACIS (NOAA Regional Climate Centers), National Weather Service API (api.weather.gov)Hurricane farm and ranch exposureUse when an agricultural lender, crop insurer, co-op or extension office needs to know which farm counties a hurricane will hit and how hard. Maps the forecast and best track to counties, totals the rain that fell or is forecast, checks flood alerts, and returns a county-by-county exposure list for outreach and claims staffing.8 toolsOpen
Uses NASA POWER, ACIS (NOAA Regional Climate Centers), National Weather Service API (api.weather.gov)Irrigation district water demand outlookUse when an irrigation district manager is planning deliveries for the next two weeks. Reads recent evapotranspiration, rainfall and temperature across the district, compares them with normals, and reads the forecast, then estimates whether demand will rise and which canals or laterals to prepare for.5 toolsOpen
Uses Element 84 Earth Search (Sentinel-2 L2A), ACIS (NOAA Regional Climate Centers), NASA POWERSatellite crop stress scouting planUse when, mid-season, an agronomist, crop consultant or farm manager wants to know which parts of a field to scout first. Finds clear Sentinel-2 scenes, measures vegetation and moisture indices by zone, explains lagging zones with rainfall and soil moisture, and renders the worst zone so a scout can walk straight to it.6 toolsOpen
Uses National Weather Service API (api.weather.gov), ACIS (NOAA Regional Climate Centers), NASA POWER, US Energy Information AdministrationHeat wave peak load checkUse when a utility load forecaster or grid operations planner needs to check a coming heat wave against recent demand and history. Reads the hourly forecast and heat alerts for the service area, recent and last-year temperatures, the balancing authority's daily demand from EIA and the climate normal, then flags peak risk days.7 toolsOpen
