pyrtlib.tb_spectrum.TbCloudRTE.execute#

TbCloudRTE.execute(only_bt: bool = True) → Union[DataFrame, Tuple[DataFrame, Dict[str, ndarray]]]#

This function computes Brightness Temperature and other radiometric parameters.

Parameters:: only_bt (bool) – If True returns only brightness temperature. Default to True.

Returns a pandas dataframe containing:

tbtotal:
brightness temperature (K) includes cosmic background; indexed by frequency and elevation angle

tbatm:
atmospheric brightness temperature (K), no cosmic; background;indexed by frequency and elevation angle

tmr:
mean radiating temperature of the atmosphere (K); indexed by frequency and elevation angle

tmrcld:
mean radiating temperature (K) of the lowest cloud layer; indexed by frequency and elevation angle

taudry:
dry air absorption integrated over each ray path (Np); indexed by frequency and elevation angle

tauwet:
water vapor absorption integrated over each ray path (Np); indexed by frequency and elevation angle

tauliq:
cloud liquid absorption integrated over each ray path (Np); indexed by frequency and elevation angle

tauice:
cloud ice absorption integrated over each ray path (Np); indexed by frequency and elevation angle

and with only_bt=False also a dictionary containing:

taulaydry:
dry air absorption integrated over each ray path (Np); indexed by frequency, elevation angle and height profile

taulaywet:
water vapor absorption integrated over each ray path (Np); indexed by frequency, elevation angle and height profile

taulayliq:
cloud liquid absorption integrated over each ray path (Np); indexed by frequency, elevation angle and height profile

taulayice:
cloud ice absorption integrated over each ray path (Np); indexed by frequency, elevation angle and height profile

srho:
water vapor density integrated along each ray path (cm); indexed by elevation angle

swet:
wet refractivity integrated along each ray path (cm); indexed by elevation angle

sdry:
dry refractivity integrated along each ray path (cm); indexed by elevation angle

sliq:
cloud ice density integrated along each ray path (cm); indexed by elevation angle

sice:
cloud liquid density integrated along each ray path (cm); indexed by elevation angle

Returns:: A pandas Dataframe with the brigthness temperature simulated. If only_bt = False it also returns all intermediate RT variables.
Return type:: Union[pandas.DataFrame, Tuple[pandas.DataFrame, Dict[str, numpy.ndarray]]]
