- define object
o=obj_new('cws_read',xrange=[1500,2800],yrange=[2800,3400],scale=0.3)
, define date and time
o->set_date,2008,6,13,12,0
- read coast vector
coast=o->coast_line(/vector)
- set cloud property
o->set_product,'ctp'
- set CREW algorithm
o->set_group,'AWG'
- read and display data
ctp1=o->get_data()
window,1
view2d,ctp1,/cool,/colo,no_data_idx=where(ctp1 le 0),coast_vec=coast,title='EUM ctp', min=200
- read and display cloud top pressure for another algorihtm
o->set_group,'CMS'
ctp2=o->get_data()
window,2
view2d,ctp2,/cool,/colo,no_data_idx=where(ctp2 le 0),coast_vec=coast,title='CMS ctp',min=200
- display the difference of the two datasets
window,3
view2d,ctp1-ctp2,/cool,/colo,no_data_idx=where((ctp1 le 0) or (ctp2 le 0) or (abs(ctp1-ctp2) gt 150)),coast_vec=coast,title='difference ctp AWG-CMS',min=-150,max=150
