i am have one
small doubt (just for the sake of confirmation) that while making
zonal/meridional/box averages of ocean data lets say SST for the region
x=20E:140E and y=90S:90N so does the ferret considering land region also
for averaging or it is just averaging the ocean region in that box
area. Because if ferret is making the averages considering the land part
then the zonal/meridional/box averages of ocean data is wrongly
calculated and interpreted.
i hope the land values (NAN if no data) are automatically taken care by the ferret while making zonal/meridional/box averages. is it so?
Apart from that how to get the area of ocean basin ? suppose i want to calculate total heat content of global ocean in joules (a line plot) so how to get the global ocean area only such that
let OHC=heat[z=0:700@ave,x=@ave,y=@ave] !! units are j/m^2
let TOHC=OHC*(global ocean area) !! units are j, TOHC=total OHC
is global ocean area is the complete box (i.e. x=360*110*1000, y=180*110*1000) if it is so then this is covering land region also along with ocean region but our variable is defined over ocean only not on land. how to get the desired result for ocean area only ? please help me to get rid out of this puzzle.
