    Description

      Arctic dataset contains a MIME format called GRIB - General
      Regularly­distributed information in Binary form http://en.wikipedia.org/wiki/GRIB . GRIB is a well known data format which is a concise data format used in meteorology to store historical and
      weather data. There are 2 different types of the format ­ GRIB 0, GRIB 2. The focus will be on GRIB 2 which is the most prevalent. Each GRIB record intended for either transmission or storage contains a single parameter with values located at an array of grid points, or represented as a set of spectral coefficients, for a single level (or layer), encoded as a continuous bit stream. Logical divisions of the record are designated as "sections", each of which provides control information and/or data. A GRIB record consists of six sections, two of which are optional:

      (0) Indicator Section
      (1) Product Definition Section (PDS)
      (2) Grid Description Section (GDS) ­ optional
      (3) Bit Map Section (BMS) ­ optional
      (4) Binary Data Section (BDS)
      (5) '7777' (ASCII Characters)
