Composite snow_age fails (no 'area') after composite cloud_phase #2724
Description
Describe the bug
Producing the snow_age composite after the cloud_phase composite fails.
I am testing with some VIIRS data in .h5 format.
To Reproduce
from satpy.scene import Scene
from glob import glob
coast_dir = '/opt/gshhg'
all_overlays = { 'coast': {'level':1} }
myfiles = glob("data/*h5")
scn = Scene(filenames=myfiles, reader='viirs_sdr')
wanted = 'cloud_phase'
scn.load([wanted])
lcn = scn.resample('antarctica')
print('ATTRS for %s = %s' % (wanted, lcn[wanted].attrs))
lcn.save_dataset(wanted, 'test.%s.png' % wanted, overlay = {'overlays': all_overlays, 'coast_dir':coast_dir})
wanted = 'snow_age'
scn.load([wanted])
lcn = scn.resample('antarctica')
print('ATTRS for %s = %s' % (wanted, lcn[wanted].attrs))
lcn.save_dataset(wanted, 'test.%s.png' % wanted, overlay = {'overlays': all_overlays, 'coast_dir':coast_dir})Expected behavior
Both composites created
Actual results
