Record of global temperature series in the ClimGen database It is important to keep this record up-to-date when new global temperature are added to the database. All temperatures in these files must be expressed as changes from the 1961-1990 mean. There are two main sets, those associated with a particular GCM and those not associated with a particular GCM. Their filenames are structured as follows: (1) GCMidentifier__SCENARI.ann (2) specialseries__sSCENAR.ann For set (1), the first 15 characters must be a GCMidentifier that EXACTLY matches the GCM identifier used for the pattern files. (1) GCM-associated global temperature changes. e.g. cccma_cgcm31___A1B_MG1.ann The GCM identifier usually begins with the institution name, then the GCM name, and decimal points are usually removed (in the example above, it is actually CGCM3.1). The scenario identifier usually begins with 4 characters to indicate the scenario, followed by 3 characters to indicate the source of the temperature data. These are the scenario identifiers currently in use: A1B_ = SRES A1B marker scenario A1FI = SRES A1FI marker scenario A1T = SRES A1T marker scenario A2 = SRES A2 marker scenario B1 = SRES B1 marker scenario B2 = SRES B2 marker scenario RC26 = RCP2.6 scenario (sometimes called RCP3-PD) RC45 = RCP4.5 scenario RC60 = RCP6.0 scenario RC85 = RCP8.5 scenario The sources currently in use: MG1 = from MAGICC5.2 (as used by IPCC AR4) tuned to fit the single given GCM M61 = from MAGICC6 tuned to fit the single given GCM GG1 = directly from the single given GCM (2) Global temperature changes not associated with a particular GCM There is no fixed convention, so every file needs to be described individually here. However, the scenario identifier should begin with 's'. NERC QUEST-GSI project: Global temperature changes following same shape as MAGICC5.2 tuned to HadCM3 under A1B, but then scaled to have the desired amount of warming at 2050. sA1B_10 = A1B shape but scaled to 1.0 degC warming in 2050 sA1B_15 = A1B shape but scaled to 1.5 degC warming in 2050 sA1B_20 = A1B shape but scaled to 2.0 degC warming in 2050 sA1B_25 = A1B shape but scaled to 2.5 degC warming in 2050 sA1B_30 = A1B shape but scaled to 3.0 degC warming in 2050 sA1B_35 = A1B shape but scaled to 3.5 degC warming in 2050 sA1B_40 = A1B shape but scaled to 4.0 degC warming in 2050 DECC/Defra AVOID project: Global temperature changes from a probability ensemble (with perturbed physical parameter values) of MAGICC5.2 simulations carried out by Jason Lowe et al. Unless otherwise specified, the values here are from the median (50 %ile) of the distributions of runs. sFrefer = A1FI reference scenario sArefer = A1B reference scenario s1refer = 10%ile for A1B reference scenario s9refer = 90%ile for A1B reference scenario sA16r2h = A1B with 2016 peak emissions, followed by 2%/yr reduction to a high stabilised level sA16r4l = A1B with 2016 peak emissions, followed by 4%/yr reduction to a low stabilised level sA16r5l = A1B with 2016 peak emissions, followed by 5%/yr reduction to a low stabilised level s116r5l = 10%ile for sA16r5l s916r5l = 90%ile for sA16r5l sA30r2h = A1B with 2030 peak emissions, followed by 2%/yr reduction to a high stabilised level sA30r5l = A1B with 2030 peak emissions, followed by 5%/yr reduction to a low stabilised level
