| 53 | | Message de Karl Taylor sur la normalisationn des variables: |
| 54 | | All variables are considered to be in a "Category A" except the following Category B variables, which are either: |
| 55 | | |
| 56 | | - intensive in area and quantify the area of a particular type (e.g., sea_ice_area_fraction), or |
| 57 | | - extensive in area (e.g., sea_ice_volume, sea_ice_mass) |
| 58 | | |
| 59 | | The time mean of category A variable is calculated as follows: |
| 60 | | |
| 61 | | Amean = sum_over_time (f_n * H_n) / sum_over_time (f_n) |
| 62 | | |
| 63 | | where n is a time sample and f is the fraction of the cell where H exists. |
| 64 | | For category B: |
| 65 | | |
| 66 | | Bmean = sum_over_time H_n / N |
| 67 | | |
| 68 | | where N is the number of time samples. |
| 69 | | |
| 70 | | Note that when H exists over the entire grid cell (i.e., isn't restricted to a portion of the cell), f_n = 1, and Amean = Bmean. |
| 71 | | |
| 72 | | For the cases you mentioned in your email: |
| 73 | | |
| 74 | | 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. |
| 75 | | |
| 76 | | LAI: Since it is an index it might be defined even over the ocean, but we need to check. |
