pyrad.io.read_trt_traj_data(fname)[source]#

Reads the TRT cell data contained in a text file. The file has the following fields:

traj_ID yyyymmddHHMM

lon [deg] lat [deg] ell_L [km] long ell_S [km] short ell_or [deg] orientation area [km2]

vel_x [km/h] cell speed vel_y [km/h] det [dBZ] detection threshold RANKr from 0 to 40 (int)

CG- number (int) CG+ number (int) CG number (int) %CG+ [%]

ET45 [km] echotop 45 max ET45m [km] echotop 45 median ET15 [km] echotop 15 max ET15m [km] echotop 15 median VIL [kg/m2] vertical integrated liquid content maxH [km] height of maximum reflectivity (maximum on the cell) maxHm [km] height of maximum reflectivity (median per cell) POH [%] RANK (deprecated)

Standard deviation of the current time step cell velocity respect to the previous time: Dvel_x [km/h] Dvel_y [km/h]

cell_contour_lon-lat

Parameters:

fname (str) – path of the TRT data file

Returns:

A tupple containing the read values. None otherwise
