v12 v13 44 44 == Output variables for LS3MIP/CMIP6 == 45 45 46 Initiated by Olivier Boucher, and followed by Frédérique Cheruy 46 Initiated by Olivier Boucher, and followed by Frédérique Cheruy: 47 - Variables already requested for CMIP5: https://docs.google.com/spreadsheets/d/1iZ7F_KBu0kbY1iZ53fMW_QObwQf141kPkxpf6Zj5OvA/edit?usp=sharing 47 48 49 - New variables for CMIP6: https://docs.google.com/spreadsheets/d/1P0D7CIf6782coBppnRCybwfjcg4bkjVmUuqd81gPtWU/edit?usp=sharing 48 50 49 https://docs.google.com/spreadsheets/d/1iZ7F_KBu0kbY1iZ53fMW_QObwQf141kPkxpf6Zj5OvA/edit?usp=sharing 50 51 52 https://docs.google.com/spreadsheets/d/1P0D7CIf6782coBppnRCybwfjcg4bkjVmUuqd81gPtWU/edit?usp=sharing 53 54 Message de Karl Taylor sur la normalisation des variabes: 51 '''Message de Karl Taylor sur la normalisation des variables:''' 55 52 56 53 All variables are considered to be in a "Category A" except the following Category B variables, which are either: … … 59 56 - extensive in area (e.g., sea_ice_volume, sea_ice_mass) 60 57 61 The time mean of category A variable is calculated as follows: 58 The time mean of category A variable is calculated as follows: 62 59 63 Amean = sum_over_time (f_n * H_n) / sum_over_time (f_n)60 Amean = sum_over_time (f_n * H_n) / sum_over_time (f_n) 64 61 65 62 where n is a time sample and f is the fraction of the cell where H exists. 66 63 For category B: 67 64 68 Bmean = sum_over_time H_n / N65 Bmean = sum_over_time H_n / N 69 66 70 67 where N is the number of time samples. … … 73 70 74 71 For the cases you mentioned in your email: 75 76 albedo over snow-covered surface: we will need to confirm, but this would be a category B variable defined only over the portion of the cell with snow. 77 78 LAI: Since it is an index it might be defined even over the ocean, but we need to check. 72 - albedo over snow-covered surface: we will need to confirm, but this would be a category B variable defined only over the portion of the cell with snow. 73 - LAI: Since it is an index it might be defined even over the ocean, but we need to check. 79 74 80 75 … … 91 86 || Land-Hist-princeton || Land only, PGF forcing || L || 1901 || 2014 || 1 || || LMIP Tier2 || A.
