There are three different kinds of parameter names one can use: the DB-ALLe parameters, the WMO B variables and the variable aliases.
The DB-ALLe parameters, fully described in A.1, are parameters that have a special meaning to DB-ALLe: for example they can be part of the coordinate system, or space/time extremes to use to query the database. They are indicated simply with their name (for example, "lat" or "yearmin").
The WMO B variables, fully described in the WMO B table, represent all possible sorts of observed data, and are indicated in the form ``Bxxyyy'', where xxyyy are the X and Y values from the WMO table B. For more details on working with observed data, see 3.3.2. For a list of all the currently available B table descriptors, see C.1.
The variable aliases are short, easy to remember names which can be used instead of frequently used WMO B variables. For a list of all the currently available aliases, see D.
