Hi All, I am trying to write some jython scripts to make a composite views,

two things i cant figure out in my script:
1) I want  to compute and display average of a grid at every time step.

I feel there must be better way to do then loop around this to get an Average
ucar.unidata.util.Misc.getAverage(avgvariable.getSample(i).getFloats()[0]) 
--well i can live with it.

I am ok with an average but would like area average, i havent seen a direct 
function(?), is there a way to get area of each grid box? that i could multiply 
and average myself? I think i saw it somewhere  but cant find where.

2) how to access a grid at particular time subset passed as an array?
  i have a gridded dataset with N times as timeset, would like to have 
newvariables at time indices 1,2,7 or specified by time values, into a new 
variable.

so I would like to get  only a particular time subset of a grid specified by a 
time array list(either index or value). This works as part of Dataselection 
before reading dataset but cant manage it with a variable after it is loaded?

Cheers,
Suvarchal
