Quality levels by BT11-BT12 and Cloud Mask NIGHT DAY If CM==3 then QL=0; If CM==1 or CM==2 then QL=1 Day: If CM==0 then If DBT<-.1 K OR DBT> 4 K then QL=2 else If DBT<-0.05 K OR DBT> 3 K then QL=3 else If DBT <0.15 K OR DBT>2. Kthen QL=4 else QL=5 Night: If CM==0 then If DBT<-.125 K OR DBT> 5 K then QL=2 else If DBT<.130 K OR DBT> 4 K then QL=3 else If DBT <0.38 K OR DBT>3.5 Kthen QL=4 else QL=5
+ Proximity to coast and clear-sky fraction NIGHT DAY If QL>1 and (D<15 km or C<10%) then QL=QL-1 D is proximity to coast, C is fraction of clear pixels within 41×41 window
