atmosphere.getNonDispersiveWetPhaseDelay - Function

4.1.1 get the integrated nondispersive wet Atmospheric Phase Delay


Description

Function to retrieve the integrated wet Atmospheric Phase Delay (NonDispersive part) along the atmospheric path corresponding to the 1st guess water column.

Arguments





Inputs

nc

Channel number (0-based; defaults to reference channel)

allowed:

int

Default:

-1

spwid

Int standing for spectral window id (0-based). The value must be >= 0.

allowed:

int

Default:

0

Returns
Quantity

Example

 
 
w = at.getUserWH2O()  
numSpw = at.getNumSpectralWindows()  
for spwid in range(numSpw):  
        numCh = at.getNumChan(spwid)  
        print "Spectral window ", spwid, " has ", numCh, " frequency channels"  
        for n in range(numCh):  
                freq = at.getChanFreq(n, spwid)  
                print "Total Dispersive Wet Phase Delay at ", freq[’value’][0], freq[’unit’], " for 1.0 air mass: ",\  
                      (at.getDispersiveWetPhaseDelay(n, spwid)[’value’][0])/(w[’value’][0]), " degrees per mm of water vapor (",\  
                      ((100*at.getDispersiveWetPhaseDelay(n, spwid)[’value’][0])/(w[’value’][0]))/(at.getNonDispersiveWetPhaseDelay(n,spwid)[’value’][0]/w[’value’][0]),\  
                      "% of the Non-dispersive one )"
