metNames2oceNames: Convert met Data Name to oce Name

In oce: Analysis of Oceanographic Data

Convert met Data Name to oce Name

Description

Interoperability between oce functions requires that standardized data names be used, e.g. "temperature" for in-situ temperature. Very few data-file headers name the temperature column in exactly that way, however, and this function is provided to try to guess the names. The task is complicated by the fact that Environment Canada seems to change the names of the columns, e.g. sometimes a symbol is used for the degree sign, other times not.

Usage

metNames2oceNames(names, scheme)

Arguments

names	a vector of character strings with original names
scheme	an optional indication of the scheme that is employed. This may be "ODF", in which case ODFNames2oceNames() is used, or "met", in which case some tentative code for met files is used.

Details

Several quantities in the returned object differ from their values in the source file. For example, speed is converted from km/h to m/s, and angles are converted from tens of degrees to degrees. Also, some items are created from scratch, e.g. u and v, the eastward and northward velocity, are computed from speed and direction. (Note that e.g. u is positive if the wind blows to the east; the data are thus in the normal Physics convention.)

Value

Vector of strings for the decoded names. If an unknown scheme is provided, this will just be names.
