branded suffix incorrect for tslsi #34
Description
@JamesAnstey @znicholls: The variables with CMIP6 compound names day.tslsi and 3hr.tslsi are supposed to be unmasked over both land and sea ice. There is no CF-defined areatype for the combination of these two area types, so in the data request the masking is indicated in the cell_methods informally (and acceptably) by placing the information in parentheses, for example: cell_methods = " area: mean (over land and sea ice) time: point".
The code that creates branded variable names is unaware of this specification and so assigns "u" to the areaLabel. The code should look for "land and sea ice" and assign "lsi" as the areaLabel (note in "lsi": the first letter is a lower case L for "land").
