mwrpy 1.0.2

Python package for Microwave Radiometer processing in ACTRIS

MWRpy

MWRpy is a Python software to process RPG Microwave Radiometer data and is developed at the University of Cologne, Germany as part of the Aerosol, Clouds and Trace Gases Research Infrastructure (ACTRIS).

The software features reading raw data, Level 1 quality control, generation of Level 2 data products and visualization and is based on the IDL code mwr_pro.

The netCDF data format including metadata information, variable names and file naming is designed to be compliant with the data structure and naming convention developed in the EUMETNET Profiling Programme E-PROFILE.

Installation

From PyPI:

python3 -m pip install mwrpy

From GitHub:

git clone https://github.com/actris-cloudnet/mwrpy.git
cd mwrpy
python3 -m venv venv
source venv/bin/activate
pip3 install --upgrade pip
pip3 install .

MWRpy requires Python 3.10 or newer.

Configuration

The folder mwrpy/site_config/ contains configuration files for each instrument type, which defines the input and output data paths etc. For example, this is the configuration file for RPG-HATPRO.

The folders for each site, e.g. mwrpy/site_config/hyytiala/, contain a site and instrument specific configuration file (config.yaml) and retrieval coefficients. For example, this is the configuration file for Hyytiälä.

Command line usage

MWRpy can be run using the command line tool mwrpy/cli.py:

usage: mwrpy/cli.py [-h] -s SITE [-d YYYY-MM-DD] [--start YYYY-MM-DD]
                       [--stop YYYY-MM-DD] [-p ...] [{process,plot}]

Arguments:

Short	Long	Default	Description
-h	--help		Show help and exit.
-s	--site		Site to process data from, e.g, hyytiala. Required.
-d	--date		Single date to be processed. Alternatively, --start and --stop can be defined.
	--start	current day - 1	Starting date.
	--stop	current day	Stopping date.
-p	--products	1C01, single, multi	Processed products, e.g, 1C01, 2I02, 2P03, single, see below.

Commands:

Command	Description
process	Process data and generate plots (default).
plot	Only generate plots.

Data types

Level 1

• 1B01: MWR brightness temperatures from .BRT and .BLB/.BLS files + retrieved spectrum
• 1B11: IR brightness temperatures from .IRT files
• 1B21: Weather station data from .MET files
• 1C01: Combined data type with time corresponding to 1B01

Level 2

• 2I01: Liquid water path (LWP)
• 2I02: Integrated water vapor (IWV)
• 2P01: Temperature profiles from single-pointing observations
• 2P02: Temperature profiles from multiple-pointing observations
• 2P03: Absolute humidity profiles
• 2P04: Relative humidity profiles (derived from 2P01/2P02 + 2P03)
• 2P07: Potential temperature (derived from 2P01/2P02 + 2P03)
• 2P08: Equivalent potential temperature (derived from 2P01/2P02 + 2P03)
• single: Single pointing data product (including 2I01, 2I02, 2P01, 2P03)
• multi: Multiple pointing data product (including 2P02, 2P04, 2P07, 2P08)
