How green and healthy the land is (PACE)
What it measures. Provides worldwide maps of vegetation health indicators derived from surface reflectance, including familiar greenness measures plus several new ones enabled by PACE's many color bands, covering things like chlorophyll, water content, and snow.
How it's made. Derived from the OCI instrument on NASA's PACE satellite, processed into global gridded maps (Level 3) with clouds masked out.
How & where you'd use it. Used to monitor crop and forest health and greenness, track vegetation stress and seasonal changes, and study land ecosystems in finer detail than older sensors allow.

Official description
LANDVI suite provides vegetation and land-surface indices derived from surface reflectance. Six of the indices are heritage, and four are hyperspectral-enabled. Users should see documentation for more details. Users should also note that the L3M product is masked for clouds. Geophysical variables in this suite include: - ndvi — Normalized Difference Vegetation Index (unitless) - evi — Enhanced Vegetation Index (unitless) - cire — Chlorophyll Index Red Edge (unitless) - pri — Photochemical Reflectance Index (unitless) - car — Carotenoid Content Index (unitless) - cci — Chlorophyll–Carotenoid Index (unitless) - mari — Anthocyanin Reflectance Index (unitless) - ndii — Normalized Difference Infrared Index (unitless) - ndwi — Normalized Difference Water Index (unitless) - ndsi — Normalized Difference Snow Index (unitless)
