attribute	NC_GLOBAL	comment	String	In order to be compliant with the EASE Grid specifications, the following modifications were made to the source files: 1) For each data variable plus the latitude and longitude variables, the two dimensional x-y grid was rotated clockwise by 90 degrees, resulting in geographical orientation where the Greenwich Meridian runs parallel to the y (rows)-axis from the North Pole at the grid center to the middle of the x (columns)-axis at the bottom edge of the grid and -90 degree E meridian runs parallel to the x (columns)-axis from the North Pole at the grid center to the middle of the y (rows)-axis at the left edge of the grid.: 2) two coordinate variables (columns and rows) were added that correspond to the columns and rows dimensions (units of m). In addition, the time variable was modified to put all of the files in the dataset on the same base time (seconds since 1970-01-01T00:00:00Z).

attribute	NC_GLOBAL	history	String	Data files were obtained from NCEI at https://www.ncei.noaa.gov/data/avhrr-polar-pathfinder-extended/access/. For each data variable plus the latitude and longitude variables, the two dimensional x-y grid was rotated clockwise by 90 degrees, resulting in geographical orientation where the Greenwich Meridian runs parallel to the y (rows)-axis from the North Pole at the grid center to the middle of the x (columns)-axis at the bottom edge of the grid and -90 degree E meridian runs parallel to the x (columns)-axis from the North Pole at the grid center to the middle of the y (rows)-axis at the left edge of the grid. To coordinate variables (columns and rows) were added that correspond to the columns and rows dimensions. The coordinate variables have units of meters. The timestamp was made consistent across all files by converting to seconds since 1970-01-01T00:00:00Z. Metadata were alter to be in compliance with CF and ACDD standards.

attribute	cloud_type	meanings	String	Cloud type value has two digits, i.e. XX, the ones place X (the first X from left), representing cloud type from CASPR algorithm, and the tenth place X representing cloud type from CLAVR algorithm. For CLAVR algorithm the tenth place X meanings: 0=clear or partly cloudy,1=fogs,2=liquid,3=mixed phase,4=glaciated,5=cirrus6=cirrus over lower,7=unused,8=unused,9=missing. For CASPR algorithm the ones place X meanings: 0=clear,1=cirrus,2=low stratus,3=warm,4=cold,5=water6=ice,7=Polar stratospheric cloud (PSC),8=unknown,9=missing.
