mwr_l12l2
This repository contains tools for running optimal estimation retrievals for humidity and temperature profiling for ground-based microwave radiometers in combination with a model background. This encompasses tools for requesting the needed ECMWF forecast data, preprocessing tools for running TROPoe as well as postrocessing functions to extract quality-controlled E-PROFILE level 2 NetCDF formats. The package contains pre-computed a priori statistics for radiosonde sites representing typical European climates. Each instrument needs an own config file.
The operational service of E-PROFILE uses this package to run centralised near real-time retrievals and generate level2 NetCDF messages from its network of ground-based microwave radiometers.
