Dear Researchers I am doing a study regarding effect of climate change on a very small catchment. I need future climate data for period 2050-2060s. I have few questions I will be thankful if you share your experience and give suggestions:
1: How many Climate models exist in CMIP5? What are RCP4.5 and RCP8.5 ?How many models exist in RCP 4.5 and RCP 8.5?
2. I have read there are 40 models for RCP4.5 and RCP 8.5 am i right? Among RCP 4.5 and RCP8.5 if i want to select some suitable models for my catchment what will be the procedure?
3. Dose spatial resolution mater for small catchment having watershed 200km square?
Dear Muhammad, RCP4.5 and RCP8.5 are different representative concentration pathways corresponding to different possible scenarios, all of which are considered possible depending on how much greenhouse gases will be emitted. Regarding the period you are interested in, the RCP8.5 project a global warming of about 2deg compared to the 1.5deg in RCP4.5 (this is a CMIP5 models ensemble average). If you want to focus on small spatial domains (you mentioned 200km) you could decide to get the 10 models with the higher resolution providing both scenarios:
CCSM4,
CMCC-CMS
CMCC-CM
CNRM-CM5
HadGEM2-CC
HadGEM2-ES
INM-CM4
IPSL-CM5-MR
MIROC5
MRI-CGCM3
