Due to a major bug in the simulation configuration all runs except driven by piControl climate were retracted and tagged as do not use.When branching the historical runs from the piControl ones in 1861, the model was told to switch from constant to transient CO2. But instead the model assumes no CO2, leading to a sudden and complete shutdown of t..
All simulations from VISIT model have been rerun. This activity mainly included a new pre-processing of land use data. The responsible modeler considers the differences to be very small, yet we keep the old version in a hidden folder at DKRZ. We will make the replaced data available to you on request.
In ORCHIDEE runs with land use change (i.e., histsoc, 2005soc,
rcp26soc and rcp60soc), a bug on soil carbon change was detected. It
will affect the following output variables: rh, clitter, csoil, and
ecoatmflux (nbp). A new version of outputs will be uploaded in about one
CLM4.5 GFDL-ESM2M extended picontrol run (1861-2099) were not
kept at a constant, pre-industrial level. Instead, a constant,
present-day value of 367 ppmv was used. Those runs were replaced at both, DKRZ storage and ESGF.This is an update to this caveat entry.
In WaterGAP2, an inconsistent handling of total actual water consumption (atotuse) has been detected, which leads to negative values of water consumption. For a more detailed description please see Caveat_WaterGAP2_atotuse.pdfCaveat_WaterGAP2_atotuse.pdf.The model owners recommend setting these negative values to zero.
PCR-GLOBWB reported the variable tws in values corresponding to a mass flux rate (kg/m2/s), although it is actually mass per area (kg/m2). The values should be multiplied by 86400 in order to obtain the correct tws values in kg/m2.
The picontrol run (exp. I) of CLM4.5 based on GFDL-ESM2M has been deleted and will be replaced soon. The run used an incorrect CO2 concentration (constant present-day values, instead of pre-industrial ones).EDIT: This issue has been resolved, see here.
The variable pirrww has been corrected for the models LPJmL and pDSSAT in order to reflect the correct variable definition according to the protocol. This was achieved by applying correction factors (see general remark on crop models pirrww variable).To achieve this pDSSAT values for maize, soy and wheat were multiplied by 0.75.
Some ISIMIP2a simulations were erroneously labelled with "nosoc", these have now been corrected:"nosoc" files from the impact models LPJ-GUESS, ORCHIDEE, JULES-UoE have been relabelled to "varsoc""nosoc" files from the impact model VISIT have been relabelled to "pressoc"
For all ISIMIP2b simulations for the model CLM45, the historical simulations are not fully consistent with the simulation protocol. For the
a mixture of 2005soc and histsoc was used: transient aerosol deposition, population density for the fire model &
nitrogen deposition were used, whilst land cover and irrigation extent..
In October, 2016, the CARAIB runs using the Princeton forcing data for the 'nat' scenario were replaced. In February, 2016, the runs using the Princeton forcing data for the 'pressoc' scenario were deleted. In the case that these data were downloaded prior to deletion, they should be considered invalid and not be used.
All BOATS GCM driven data for fishing runs (GFDL-ESM2M & IPSL-CM5A-LR, for all 4 RCPs.) have been replaced.In the old BOATS runs, fishing effort was not kept constant after 2005, which had created some wiggles in the future runs. This has been changed now, resulting in more smooth trajectories.
Do to several inconsistencies in the original model data, the following files were replaced on 19 December, 2017:EwE (adriatic-sea): all filesEwE (baltic-sea): all GFDL-ESM2M files, all IPSL-CM5A-LR rcp45 and rcp60 IPSL filesEwE (east-bass-strait): all IPSL-CM5A-LR filesEwE (med-glob):
all gfdl-reanalysis files except wo-diaz_fishing_no-oa_tc10c..
All ISIMIP2b ORCHIDEE biomes files for the variable burntarea were
replaced. The new monthly burntarea data are identical to the formerly
published monthly burntarea data, multiplied by the number of days per
month and capped at 100%. The new files are consistent with the protocol
definition of monthly burntarea.
The following files were replaced on 14 November, 2017:jules-w1_hadgem2-es_rcp26_2005soc_co2_evap_global_monthly_2006_2099.nc4jules-w1_hadgem2-es_rcp26_2005soc_co2_qr_global_monthly_2006_2099.nc4jules-w1_hadgem2-es_rcp26_2005soc_co2_qsb_global_monthly_2006_2099.nc4jules-w1_hadgem2-es_rcp26_2005soc_co2_qs_global_monthly_2006_2099.
Other than the files mentioned in the entry ISIMIP2b: Water (global) JULES-W1 hadgem2-es_rcp26_2005soc_co2 2006-2099 files replaced the files from the JULES-W1 model are missing the final time step of data. The missing timesteps are the 31/12/2299 for the picontrol runs, the 31/12/2005 for the historical runs and the 31/12/2099 or 2299 for the r..
The missing values have now been replaced by valid data.HistoryPosted by Jacob Schewe on July 6, 2017Note that a number of land grid cells are filled with missing values (NaN) in
the MATSIRO varsoc results, even for runoff and discharge. See the
attached maps and table and the map below for the locations of these cells (example for the

The grid shift in the LPJ-GUESS Fast-Track data has now been corrected. HistoryJune 19, 2017The simulation data from LPJ-GUESS for the agriculture sector have been found to be incorrectly shifted by one cell north east. This issue has not been corrected and applies to the data stored on the ESGF and DKRZ servers.
The biomes simulations from DLEM using the climate input from IPSL-CM5A-LR have been replaced. For the new simulations, DLEM used a different strategy to reach the equilibrium
state. Small differences can be expected between old and new IPSL runs.
The new strategy was already used for the simulations using the climate input from GFDL and MIROC5.
The routing scheme in the DBH model has been modified, resulting in an update to the daily discharge data for the nosoc and varsoc simulations. In the new data, the routing model was run with a sub-daily step instead of the previous daily step to obtain smoother daily discharge.
Average wheat yields in some individual (clusters of) grid cells
exhibit a systematic difference between the historical run and the
other (picontrol, RCP) runs. See the attached map and timeseries plots
for an illustration of the issue. A potential reason may be that the
model grows winter wheat in the one case, and spring wheat in the
A variable name change has been applied to CARAIBs pft and frc data at DKRZ today:frc -> pftpft -> pft-2storeysThe reason behind is to have the CARAIB data more comparable to PFT from other biomes models. Please read the variable description below explaining the difference between frc (now pft) and pft (now pft-2storeys)The variable pft-2st..
The ISIMIP2a oceanic input data from
GFDL (both reana and scen) has an irregular grid north of 65°N and had
not been correctly regridded. Therefore the corresponding outputs from the marine ecosystems and fisheries models in that
region are flawed.
Shifts in LPJmL and LPJ-GUESS files have been
corrected. Issue in pDSSAT and pAPSIM (southeast coastline cells missing) persists because it is due to
erroneous masking and cannot be corrected as easily. HistoryMarch 3, 2017
(Some) outputs from
LPJmL are shifted north by one cell (0.5°). There also appears to be a
nort-east shift in LPJ..
PFT specific gpp and npp data have been retracted from the DKRZ server on March 9th, 2017. LPJmL group discovered PFT-specific GPP and NPP of the "c3_perennial_grass" PFT and "c4_perennial_grass" PFT to contain wrong values under certain circumstances. While the PFT-specific GPP and NPP outputs for all the other PFTs should be fine they think it ..
Three files from JULES-TUC were replaced. The problem was in the ET files during the aggregation of the
components: soil, canopy and sublimation. The replaced files were: water_global/JULES-TUC/hist-obs/wfdei/jules-tuc_wfdei_hist_nosoc_co2_evap_monthly_1971_2010.nc4 water_global/JULES-TUC/hist-obs/gswp3/jules-tuc_gswp3_hist_nosoc_co2_evap_monthl..
The data from LPJ-GUESS for the variable fapar were mistakenly reported as monthly sums rather than averages. This will be corrected and new files uploaded. Also a number of variables have names are different from what is prescribed in the simulation protocol.fixed on April 6th with the following adatptions:fapar addedfirefrac renamed to burntare..
Fixes for an inconsistency between the river network and the location of
dams and reservoirs as well as a small error in the spin-up procedure
that affected our runs for all 4 forcing data sets. In addition, the
updated results for the Princeton forcing data set are based on the
corrected version of the input data now.
