Abstract
With the recent launch of the Soil Moisture and Ocean Salinity (SMOS) mission, and the future Aquarius and Soil Moisture Active Passive (SMAP) missions being planned for 2011 and 2014, respectively, the remote sensing community is becoming engaged in airborne campaigns for their validation. Given the financial and logistical constraints on the area that can be covered by airborne simulators in such campaigns, scientifically sound advice on the fractional footprint coverage requirements by campaigns for these low resolution sensors is of paramount importance, to ensure the usefulness of the validation campaigns. Using high resolution airborne data from an extensive airborne campaign in south-eastern Australia the fractional coverage requirement for L-band passive microwave satellite missions is assessed. It is found that only in the case of particularly homogeneous areas can this fractional coverage be considerably reduced.
