What new in CMIP-6 ??

New in CMIP-6

CMIP-6 is new generation of Coupled Model Inter-comparison Projects (CMIP) after CMIP-5 and fifth assessment report (AR5) of IPCC.

1: Total institute participated: 49 Institute in CMIP-6.
2: Total experiment: more than 300 Experiment
3: Variant Label: There are r_i_p_f whereas in CMIP-5 there was only r_i_p

Where

r= realization_index 

i= initialization_index

p= physics_index 

f= forcing_index which new in CMIP-6
4: Emission scenarios: Shared Socioeconomic Pathways (SSPs) in place of Representative Concentration Pathways (RCPs).

Shared Socioeconomic Pathways (SSPs) in CMIP-6

1: SSP126 which is update of RCP2.6 but based on SSP1

Data of future scenario (2015-2100) having low radiative forcing by the end of century. Similar to RCP2.6 and based on shared socioeconomic pathways (SSP1).

2: SSP245 which is update of RCP4.5 but based on SSP2

Data of future scenario (2015-2100/2300) having medium radiative forcing by the end of century. Similar to approximately RCP4.5 and based on shared socioeconomic pathways (SSP2).

3: SSP460 which is update of RCP 6.0 but based on SSP4

Data of future scenario (2015-2100) having medium radiative forcing by the end of century. Similar to approximately RCP 6.0 and based on shared socioeconomic pathways (SSP4).

4: SSP585 which is update of RCP 8.5 but based on SSP5

Data of future scenario (2015-2100/2300) having high radiative forcing by the end of century. Similar to approximately RCP 8.5 and based on shared socioeconomic pathways (SSP5).

Other SSPs in CMIP-6

5: SSP119 (Mitigation)

Future data (2015-2100) and low radiative forcing (1.9 W/m2) at end of 2100 and based SSP1.

6: SSP370 (baseline)

Future scenario data (2015-2100) based on SSP3 and having high radiative forcing (7.0 W/m2) near 2100. Fills gap in RCP forcing pathways between 6.0 and 8.5 W/m2.  

7: SSP3-LowNTCF (Mitigation):

This is mitigation scenario types based on SSP3 and having the 6.3 W/m2 radiative facing near 2100.

8: SSP434 (Mitigation):

Future scenario data (2015-2100) based on SSP4 and low radiative forcing (3.4 W/m2) near 2100. Fills gap in RCP forcing pathways between 4.5 and 2.6 W/m2.

9:SSP534-OS (Mitigation):

This is mitigation scenario types based on SSP5 and having the 3.4 W/m2 radiative facing near 2100.

Note:

Here in CMIP-6 the SSPs scenarios data are providing from 2015-2100 whereas  historical data are given from 1850 to 2014.
