Interannual variability in North American grassland biomass/productivity detected by SeaWinds scatterometer backscatter [PDF]

open access: yes, 2005
We analyzed 2000–2004 growing-season SeaWinds Ku-band microwave backscatter and MODIS leaf area index (LAI) data over North America. Large anomalies in mid-growing-season mean backscatter and LAI, relative to 5-year mean values, occurred primarily in the

Woody plant cover estimation in drylands from Earth Observation based seasonal metrics [PDF]

open access: yes, 2016
peer reviewedFrom in situ measured woody cover we develop a phenology driven model to estimate the canopy cover of woody species in the Sahelian drylands at 1 km scale. The model estimates the total canopy cover of all woody phanerophytes and the concept
