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.

• podman: https://podman.io/

  • on some distros the package slirp4nets is not installed. Make sure to have it for root-less execution of podman. Available through apt

• TROPoe: https://hub.docker.com/r/davidturner53/tropoe

  • Make sure to pull the container with podman:

    podman pull docker.io/davidturner53/tropoe

• for using ECMWF forecasts:

  • libeccodes0 and libeccodes-tools: grib file utilities available through apt
  • mars: command line utility to obtain ECMWF data, see https://confluence.ecmwf.int/display/UDOC/MARS+user+documentation
