Version Summary
Version Summary
Version 3 Aquarius L2 Swath Single Orbit Soil Moisture observations are valid over a wider range of brightness temperatures than Version 2 measurements. Version 3 brightness temperatures are no longer re-calibrated before soil moisture retrievals. The soil moisture model parameters were updated in Version 3. Algorithm parameters are constant over all land cover classes.
