and Implications for SMAP
IGARSS 2010, Honolulu, Hawaii
Hornbuckle et al., Dew and L-band Backscatter, Implications for SMAP?
European Space AgencySoil Moisture and Ocean Salinity (SMOS) in orbit.
L-band brightness temperature.
Spatial resolution: 40 km.
Global-scale measurements of soil moisture at L-band...
NASA Soil Moisture Active-Passive (SMAP)scheduled launch in 2014/2015.
L-band brightness temperature and backscatter.
Spatial resolution: 10 km.
Hornbuckle et al., Dew and L-band Backscatter, Implications for SMAP?
Are changes in backscatter over short periods of timeonly due to changes in soil moisture?
