Name: | Ocean mixed layer thickness defined by sigma theta 0.01 kg/m3 | Abbreviation: | mlotst010 | Unit: | m | paramId: | 151225 |
Description: | The mixed layer depth is defined as the ocean depth at which sigma-theta has increased by 0.01 kg m-3 relative to the near-surface value at 10 m depth |
S2S details
Validity | Daily averaged |
Comment | Land points should be set as missing values. Computation of daily average depends on the model (e.g. it can be a direct model output or computed one from instantaneous values at 0, 6, 12 and 18Z etc) |
