Particle position output from the FLEXPART dispersion model for a test case for use with the WaterSip moisture source diagnostic

This dataset contains configuration files and model output to test with the Lagrangian moisture source and transport diagnostic WaterSip in version 3.2.

A first set of files comprises individual particle output in shortposit files from the Lagrangian particle transport model FLEXPART in version 10.4. This simulation has been set up for the time period 19 July to 25 August 2022 with ERA5 reanalysis data. The atmosphere has been discretized into 10 million air parcels, each of them with a mass given in the part_mass file. The FLEXPART code to generate the particle output in FORTRAN90 is provided to enable conducting similar FLEXPART runs.

A second set of files comprises the setup of a test case for the WaterSip diagnostic. A configuration file is provided which sets up a domain over Scandinavia (54-71ºN, 4-32ºE), and runs an analysis for the time period 20 July to 20 August 2022. Additional input files for the topography and land sea mask required by WaterSip are provided in netCDF format. The output files from running WaterSip with this setup are alos provided (Scandinavia_2022_global_6h.tar).

In order to set up WaterSip run, the content of this archive needs to be arranged in the following directory structure:

./INPUT_WATERSIP.Scandinavia_2022_global_6h

./static/etopo5.nc

./static/ERA_sea_mask_inv.nc

./input/partposit_*

./output/

./WaterSip (compiled executeable)

The WaterSip code repository is accessible at https://git.app.uib.no/GFI-public/watersip.
