Contents

Display a cloud property of one algorithm on the MSG disk

o=obj_new('cws_stats')
o->set_product,'cth'
o->set_group,'CMS'
o->set_date,2008,6,13,12,15
o->make_image, /single
obj_destroy, o

CMS cloud top height

Display a cloud property of all algorithms on the MSG disk

o=obj_new('cws_stats')
o->set_product,'ctp'
o->set_date,2008,6,13,12,00
o->make_image, /no_track

obj_destroy, o

latitudinal mean of cloud top height

cloud top pressure histogram

Reading two datasets and have a look at the difference

; 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='AWG ctp', min=200

; read and display cloud top pressure for another algorithm
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
