Issue to document mwi_wsf-m1_delivery_01223024.tgz from Quanhua Liu / STAR on 23 January, 2024.

A conical scanning microwave radiometer with a 1.8m antenna It measures at 6 different frequencies in the 10 to 89 GHz range (see below for details) 3 channels have full polarimetric capability (see below) resulting in 17 channels overall. The 3rd and 4th stokes vectors are obtained by digitally sampling and cross-correlating v-pol and h-pol amplitude signals. More information here: https://tinyurl.com/39evn3t4

Channel Centre frequency (GHz) Bandwidth (MHz) Polarisations Beamwidth (deg) 3dB footprint (km) NEΔT
1 10.85 500 V,H,3rd,4th 1.06 38x23
2 18.85 500 V,H,3rd,4th 0.66 23x15

"The mwi_wsf-m1 CRTM coefficients is generated by using Rosenkranz line-by-line and combined ODPS and ODAS algorithm.

83 ECMWF profiles are used."
