## Class to Hold amsr Data

### Description

The Advanced Microwave Scanning Radiometer (AMSR-2) is in current operation on the Japan Aerospace Exploration Agency (JAXA) GCOM-W1 space craft, launched in May 2012. Data are processed by Remote Sensing Systems. The satellite completes an ascending and descending pass during local daytime and nightime hours respectively. Each daily file contains 7 daytime and 7 nighttime maps of variables named as follows within the `data` slot of amsr objects: `timeDay`, `SSTDay`, `LFwindDay` (wind at 10m sensed in the 10.7GHz band), `MFwindDay` (wind at 10m sensed at 18.7GHz), `vaporDay`, `cloudDay`, and `rainDay`, along with similarly-named items that end in `Night`. See [1] for additional information on the instrument, how to cite the data source in a paper, etc.

### Details

The bands are stored in `raw` form, to save storage. The accessor function `[[,amsr-method` can provide these values in `raw` form or in physical units; `plot,amsr-method`, and `summary,amsr-method` work with physical units.
