AMSR files are provided at the FTP site, at
ftp.ssmi.com/amsr2/bmaps_v07.2 as of April 2021.
To acquire such files,
log in as "guest",
then enter a year-based directory (e.g. y2016 for the year 2016),
then enter a month-based directory (e.g. m08 for August, the 8th
month), and then download a file for the present date, e.g.
f34_20160803v7.2.gz for August 3rd, 2016. Do not uncompress
this file, since read.amsr can only read the raw files from the server.
If read.amsr reports an error on the number of chunks, try
downloading a similarly-named file (e.g. in the present example,
read.amsr("f34_20160803v7.2_d3d.gz") will report an error
about inability to read a 6-chunk file, but
read.amsr("f34_20160803v7.2.gz") will work properly.
