What's in it
- Data offered docs-verified
- MCD43A4 nadir BRDF-adjusted daily surface reflectance, 500 m · MOD11A1 / MYD11A1 daily land surface temperature and emissivity, 1 km · MOD13A1 / MYD13A1 16-day vegetation indices, 500 m
- Coverage docs-verified
- Global · MCD43A4 ~21 years (all time); MOD11A1, MYD11A1, MOD13A1, MYD13A1 ~11 years
- Resolution docs-verified
- Spatial: 500 m for MCD43A4, MOD13A1, MYD13A1; 1 km for MOD11A1, MYD11A1 (SIN grid). Temporal: daily for reflectance and LST; 16-day for vegetation indices
- Update frequency docs-verified
- Daily (new scenes added daily)
- Formats docs-verified
- COG (single-band cloud-optimized GeoTIFF)
- Access docs-verified
- Open licence: no restrictions on use unless expressly identified at or before receipt. No API key or auth in the entry. Data is in an AWS S3 bucket (astraea-opendata, us-west-2) that is Requester Pays, so an AWS account is needed to download
Useful for
- Use cases llm-inferred
- Vegetation greenness (NDVI/EVI) baseline and seasonal trend for ecological condition context, e.g. BNG habitat baseline support · Land surface temperature context for urban heat or drainage-catchment screening assessments · Multi-year surface reflectance time series for land-cover change baselining on catchment or regional scales
- Audience llm-inferred
- ecologists · GIS analysts · hydrologists · environmental consultants · remote sensing analysts
Limitations
- Constraints llm-inferred
- 1 km LST and 500 m reflectance/vegetation grids are too coarse for site-scale assessment · Most products cover ~11 years, so long-term baselines need MCD43A4 (~21 years) · Requester Pays S3 bucket requires an AWS account and incurs access charges · No MCP or API tooling listed; data must be pulled from S3 and processed by the user
