[gradsusr] time height croosection of thetae

[madhu latha]

hi

i have done in this way

'reinit'
'open d03_2010-08-01_00:00:00.ctl'
'set grid off'
'set grads off'
'set display color white'
'set lat 12'
'set lon 77'
'set t 1 145'
'set lev 950 250'
'set gxout line'
Rv = 461.5
Rd = 287.05
Cp = 1005
lv = 2.5e6
*'d t'
'define t=tc+273.14'
'define e1=6.11*exp((2.5e6/461.5)*((1/273)-(1/'t')))'
'define e = 'rh'*'e1'/100'
'define mr=0.622*'e'/('lev'-'e')'
'define eqt='t'+(2.5e6*('mr')/1005))'
'define thee ='eqt'*pow(1000/'lev',287.05/1005)'
'set gxout shaded'
''d thee'
'run cbar.gs'
