In steingod/R-mipolsat: Useful functions for handling locally processed satellite data

Description

FMCOL HDF5 collocation files containing collocated data are read and the contents (or some of the contents) are returned to R for further analysis and concatenation. This function is a generic function utilise more specialised functions. The specialised functions can be hidden or visible for ordinary usage.

The objects currently supported and their numbering is:

1. AVHRR data, a square box of channel data (reflectances or brightness temperature) and auxiliary information like observation geometry, time, number of pixels etc.

2. NWP data, Numerical Weather Prdeiction data, usually from the operational model suite.

3. STDAT, in situ measurements from GTS SYNOP or DRAU files.

4. SAFCM, NWCSAF PPS cloudtype products.

5. SAFSSI, OSISAF shortwave estimates.

6. SAFDLI, OSISAF longwave estimates.

Usage

    readfmcol(path,pattern,method,classname="cloud",station="NA",start="NA",end="NA")

Arguments

path	path to the files to read
pattern	optional regular expression pattern for files to match
method	the read functionality to use e.g. read123, read124. remember quotes.
classname	text string to search for in the HDF5 file, defaults to "cloud"
station	text string containing station identification
start	start time in the form "12jan2007", month name is locale dependent
end	end time, similar form to start time

Value

A list containing the data. Use names to see the variables.
