I am working on a model in SWAT and intend to carry out a climate change analysis. I would be very grateful if fellow researchers could suggest some ideas,data and tools for Climate Change Projections and Downscaling. Thanks for your feedback.
Is it possible to downscale CMIP5(CanESM2, HadGEM) GCMs using SDSM.
Check on http://www.metoffice.gov.uk/precis/
Yesterday we had a seminar presentation on PRECIS. Could be a viable options.
Another approach could be through cokriging and neural networks. I did a work (http://www.sciencedirect.com/science/article/pii/S136481521000318X) applying these techniques (on air quality), that can be easliy applied also for Climate Change downscaling. I.e. starting from real measurement data (to be used to make point-wise projections through neural networks) and modelling simulations (to be used in projections spatializations). It is a simple and not time-consuming approach. if you need more infos please contact me. Bests, Enrico
if you are interested, you find the paper here:

SDSM is a free user-friendly, statistical downscaling software package available at:http://co-public.lboro.ac.uk/cocwd/SDSM/
At the moment, my memory is failing to recall the name, however, Indian Institute of Tropical Meteorology used to project and downscale the climate by major basins in India a software in collaboration with some university/ institute of Britain. After doing some googling using """downscaling of climate change by Indian Institute of Tropical Meteorology, Pune"", you perhaps will find out the exact name of the model/programme/software used
SimCLIM is a useful linked-pattern scaling software package. www.climsystems.com/
Its pretty straight forward to test different emissions scenarios and climate sensitivities, projecting extreme events and running monte carlo simulations of storm surges etc. It has quite a few built in analysis tools and you can choose from different GCM patterns or run ensembles of patterns.
Graham I looked at SimClim though very good the minimum cost for students is $500 and I don't have funding at the moment. Besides I want to use freely available tools so the research can easily be replicated by anyone who is interested. I may end up with SDSM as suggested earlier or LARS-WG. But I am still open to suggestions from others. Thanks to you all for your valuable ideas.
And there would likely be additional costs to load the SimCLIM software with the gridded monthly GCM patterns and weather data as well as importing any daily or hourly weather station data you had.
If your interest is over West Africa, you probably have to wait for the CORDEX projections. The only problem is they are at 50 km. However, you can further downscale them using statistical or dynamical downscaling tools. I'm currently downscaling some CMIP5 ESMs over West Africa with a regional climate model at 25 km. I don't know how long it's gonna take or how many ESMs it will be but I'm sure to have at least 2 ESMs along with 2 RCPs each. If you are interested ...
You can use LARS-WG version 6. that use CMIP5 GCMs and fifth report IPCC scenarios.
