Cloudmap file format
The data is in Hdf5 format
date and time
cost(nlat,nlon) real
data(nlat,nlon,6) real
error(nlat,nlon,6) real
where the 6 variables in the data and error arrays are..
1. optical depth
2. particle size
3. cloud top pressure
4. cloud fraction
5. skin temperature
6. cloud top height
iteration(nlat,nlon) integer
phase(nlat,nlon) integer
latlon(nlat,nlon,2) real
for the structure of the hdf5 data set is typically shown here using
the unix command 'h5dump -H hdffile'
