Additional soil data and ocean input data now available

Posted by Martin Park on June 3, 2020

Dear ISIMIP modelers,

with this email we would like to announce:

1) the availability of an additional soil data set
2) the availability of ocean input data

1) Thanks to the initiative of Jonas, Christoph and Sam the ISIMIP3 protocol now provides an additional soil data set that meets criteria specific to the Agriculture Sector. The data are based on HWSD soil data and were aggregated to the ISIMIP 0.5° grid. The aggregation has been performed using the dominant soil class on cropland (using the 5 arc-minute MIRCA2000 cropland data) per 0.5 degree pixel. The script can be easily adjusted to process data without the cropland weighting, so that it could be used for other sectors, too. Please get in touch and align with sector coordination in case this is wanted.
For further details please refer to the README in the ISIMIP3a/InputData/geo_conditions/soil/ folder.

2) Input data for the marine-fishery sector is now available from these global models IPSL-CM6A-LR, MPI-ESM1-2-HR, UKESM1-0-LL and GFDL-ESM4. Compared to the tier 1 model list only MRI-ESM2-0 is missing because it lacks a biogeochemical model component for the ocean. Unfortunately variable availability differs for both, models and CMIP6 experiments. However, we tried to collect as much data as possible and hope to fulfill the input needs for most of the marine-ecosystem groups.
Variables cover both, physical and biological variables which were requested by the sector coordination. All data is on monthly resolution and has been remapped to a common 1° grid. It is planned to provide half degree data for the MPI-ESM1-2-HR model as it comes with a spatial resolution close to half degree.
Variable names without a hyphen refer to the original data remapped to 1°. Those with a hyphen followed by bottom, surf or vint refer to data derived from vertically resolved data. Here, vint refers to variables vertically integrated over the entire water column.
Data is available at DKRZ in the folders below: /work/bb0820/ISIMIP/ISIMIP3b/InputData/climate/ocean/uncorrected/global/monthly/

Many greetings,
the ISIMIP team at PIK
