Hi,
when computing cloud cover assessment using i.landsat.acca in G7 I
found something strange - 'cold' clouds have higher temperature than
'warm' clouds
Maximum temperature:
* Cold cloud: 287.00 K
* Warm cloud: 281.13 K
The command:
i.landsat.acca -5 -2 input_prefix=Bref output=oblc
Input data (Bref) computed by i.landsat.toar based on Landsat 5 TM.
Any idea? It's probably easy, seems to me that I am overlooking something...
Thanks! Martin
