the year comes to a close, we’d like to thank you for your
invaluable contributions to ISIMIP in 2016. Whether conducting
model runs, contributing to the development of the protocol and
input data sets, participating in the workshop, analysing ISIMIP
simulations, or supporting the organisation of ISIMIP,..
We have a few important protocol changes and
corrections that we'd like you to be aware of:
All sectors: In order to ensure a
smooth transition between the pre-industrial and historical
periods, the pre-industrial CO2 concentration needs to be set

Since a few of you have already inquired, we would like to offer
you some further explanation about the scientific motivation
behind the ISIMIP2b protocol. You can find even more detail in the
paper currently under review in Geoscientific Model
We are delighted to be able to share with you the
latest ISIMIP simulation protocol, ISIMIP2b. You can download

Replacement of WFDEI data for 2011-2013 The team responsible
for producing the WFDEI data set (which we combined with WATCH to
produce a continuous historical data set starting in 1901) have
announced a replacement of the rainfall and snowfall data for the years
2011, 2012, 2013. The problem was a processing error in the original
We are delighted to inform you that registration is now open for the
ISIMIP workshop on 22-24 June, 2016, at the Potsdam Institute for
Climate Impact Research (PIK) in Potsdam, Germany. You can find the
draft workshop program and registration form on this page. Please note that registration closes on Friday, 25 March.
We are delighted to inform you that the Focus Issue in
Environmental Research Letters on "Impacts of Extreme Weather and
Climate Events Across Sectors" is now open for submissions.
Those ISIMIP participants who have submitted an abstract for
consideration for the Focus Issue will shortly receive an official
invitation to submit.
This is to inform you that the LPJmL team has just replaced all results
for the biomeass, permafrost and water sector on the DKRZ server. The
update fixes 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 datasets.
Based on your feedback regarding the correction to the 1901-1947 Princeton data, the following decisions has been reached:
* /All/ biomes models will re-run the Princeton data set due to the significant effects on the outcomes of the model spin up.
* We recommend that other models that have used the
1901-1947 data also re-run these simulations.
As we reported to you at the end of last year, the Princeton data set
provided to you for use in the ISI-MIP simulations for the period
1901-1947 has been superceded by a corrected version. The problem was a mistake in the processing scripts, not a systematic methodological mistake, so the data were just wrong.
We are delighted to announce that the next ISI-MIP workshop
will be held in the newly opened research building at PIK, Potsdam on
22-24 June, 2016. We have chosen the date in part to give those of you
who will be attending the AgMIP workshop in the following week in France
the chance to combine your attendance of the two meetings.
As many of you are already conducting analyses of the ISI-MIP2.1a
simulation runs, we would like to ensure that you can keep track of when
modelling groups replace their simulations on the DKRZ server. For
this reason we have placed a table on the ISI-MIP website under For
Modellers>ISI-MIP2>Output Data>Uploads (link), where all fil..
We would like to ask for your help in collecting key
information about impact models participating in ISI-MIP, and the
settings used to generate simulation results, in a common document. The
goal of this exercise is to provide an accurate and comprehensive source
of information for those using ISI-MIP simulation data for scientific
We have received information from the developer, Graham Weedon, that the
WFDEI data set has now been extended such that there is a complete set
of variables up to 2013 (previously the data set ended in 2010). We
have processed these three additional years' data to the standard
ISI-MIP format and placed the files on the DKRZ server vre2.dkrz.
We would like to remind you about the session at the 2016
European Geophysical Union (EGU) meeting the we are helping to
coordinate. The session is very appropriate to the type of analyses
currently being conducted within ISI-MIP. Here is a link to the session
we would like to inform you about some further changes to the way
ISI-MIP data is uploaded and stored. Please read this email carefully
and contact us if anything is unclear. 1. vre1.dkrz.de to be replaced by vre2.dkrz.de The vre1.dkrz.de server will shortly be decommissioned and replaced with a virtual machine (VM) with the name vre2.dkrz.de.
we would like to share with you some important changes to the way that simulation data is uploaded to the DKRZ server vre1.dkrz.de.
The aim of the changes is to ensure that only ISI-MIP participants can
access the quality-checked and harmonised version (with respect to file
naming, meta data and grid definitions etc.
It has been brought to our attention that the version of the Princeton
data set used so far within ISI-MIP2.1a for the time period 1901-1947
has been replaced by a new version by the producers of the data. The version made available for ISI-MIP contains some fairly significant departures from the new version for the variables tas, tasmin, tasm..
We would like to make you aware of the following session to be held at

1) Since the official release of the ISI-MIP data we have put a lot
of effort into testing and documenting the bias correction method. We
have found that the algorithm currently used does not do exactly what we
want: In some cases, due to a technical problem, the width of the
frequency distribution of daily data is not corrected.
1. Identified problems with uploaded data First of
all, we are delighted to see that by now 13 modeling groups have already
submitted output data to our data pool at DKRZ. Along with the
delivered files we have discovered some issues regarding several
aspects of the files integrity among the majority of models. Most often
