MODIS NBAR-derived 16-days fractional cover of Photosynthetic Vegetation (PV), Non-Photosynthetic Vegetation (NPV) and Bare Soil (BS).

Abstract or Summary

Data are MODIS NBAR-derived 16-days fractional cover of Photosynthetic Vegetation (PV), Non-Photosynthetic Vegetation (NPV) and Bare Soil (BS). Fractional cover represents the exposed proportion of PV, NPV or BS within each pixel. In forested canopies the photosynthetic or non-photosynthetic portions of trees may obscure those of the grass layer and/or bare soil.

Fractional cover was derived using a linear unmixing methodology (Guerschman et al. 2009). The method uses the NDVI and the ratio of MODIS bands 7 and 6 (2100 and 1600 nm respectively).

The method was originally developed for the Australian tropical savannas and was evaluated using field measurements of grass curing in ten sites, of which six are in the tropical savannas and four are located in grasslands in the west and south east of Australia. The resulting method has been applied to the whole Australian Continent.

Keywords

There are three main thesauri that AusCover recommends:

1. Global Change Master Directory (http://gcmd.nasa.gov)
2. Climate and Forecast (CF) convention standard names (http://cf-pcmdi.llnl.gov/documents/cf-standard-names).
3. Fields of Research codes (http://www.abs.gov.au/ausstats/abs@.nsf/0/6BB427AB9696C225CA2574180004463E?
   opendocument).

Notes:

1. Replace the example GCMD and CF keywords.
2. Multiple keywords can be used, one per row.
3. TERN recommends only two levels for the FoR keywords. The FoR keyword (Ecological Applications) has been selected to cover most AusCover products.
4. Retain the explanatory paragraph with the links ("There are three....).
