Covariate module to grab coarse resolution environmental data from NCEP
NCEP(extent = c(-5, 5, 50, 60), variables = "hgt", status.bar = FALSE)
Arguments
- extent
- A numeric vector of length 4 giving the coordinates of the
rectangular region within which to carry out the analysis, in the
order: xmin, xmax, ymin, ymax.
- variables
- Character vector of which variables to select.
See NCEP.gather for more options but basic options are
*'air'* Air Temperature deg K
*'hgt'* Geopotential Height m
*'rhum'* Relative Humidity
*'shum'* Specific Humidity kg/kg
*'omega'* Omega [Vertical Velocity] Pascal/s
*'uwnd'* U-Wind Component [East/West] m/s
*'vwnd'* V-Wind Component [North/South] m/s
- status.bar
- Logical. Should a status bar be shown indicating the percentage of completion?
