This figure shows the number of times the POLDER sensor would image a point on the Earth’s surface at 52N 0E between 31st May and June 15th. POLDER was a great sensor for MVA sampling of the Earth’s surface in that it could image a particular spot up to 14 times in a single overpass – thus providing a variation in the sampling of exitant radiance through altering the view zenith angle of between the sensor and target.The sampling shown would provide pretty low Sun zenith angles (SZA) for the sample period. The greatest extent of which would be around 45 degrees for the few samples at 120 and 180 degrees solar azimuth. Given that the SZA is measured from the horizon, the rest of the samples would be prone to pretty hefty shadow.

I may even offer an explanation sometime, if I can remember that far back.  Given my current involvement in Digital Preservation issues relating to research data and outputs, it’s a little depressing to find that judicious DAT/DLTing have resulted in me drawing a blank on retrieving the paper related too these images at the moment. Take care all you Early Stage Researchers out there – this is a big issue, particularly for those of you who may be dabling with processing digital data yourselves.
