I spotted those shaky 'facts', too. One issue which concerns me greatly is ocean colour / albedo. Far too little is discussed on this issue WRT OIF.
I wonder if anyone on this list has access to such measurements? Photos are not a reliable indicator of numerically accurate albedo, unless calibrated specifically for the purpose.
