Test case for AMSR2.

test data (half orbit):
  GW1AM2_201807171248_065A_L1SGBTBR_2220220.h5

Shell script: run_amsr2.sh
==========================

This has 3 parts:

1) Convert hdf to BUFR using the standalone amsr2_hdf2bufr.exe

2) Run amsr2_main.exe, with the namelist (amsr2_main.nl) configured to perform
averaging and map to a user-defined grid.

3) Create quick-look images of the original and averaged data, using
mwipp_quicklook.py.

The python plotting script uses Cartopy: see https://scitools.org.uk/cartopy/docs/latest/

Approximate run times:
Part 1: 9 sec (hdf to BUFR)
Part 2: 15 sec (hdf read; average; re-map; BUFR write; HDF5 write)

You can inspect your output data files using tools such as h5dump (part of hdf5)
and bufr_dump (part of ecCodes), and compare with equivalent outputs in the
"reference_products" directory.

You should expect the output brightness temperatures to be consistent with the
reference outputs, to approximately 0.01K.
