DISCLAIMER:  This data should only be used for a cursory view.  There is no guarantee that this data is accurate, including time-stamps and labels.
NOTE:  The time in the cloud fraction files for the long-term SURFRAD sites indicate UTC but should be local time!
 
At some point I'll write a little program to add a time parameter that is
more conducive to plotting.  

The parameters for those files that have many parameters are:

 1) time, text format
 2) time, milliseconds since 1-1-1970, midnight UTC
 3) opaque clouds (percentage)
 4) thin clouds (percentage)
 5) sunny (yes or no)
 6) solar altitude (degrees)
 7) solar azimuth (degrees)
 8) pixel count: "outside of mirror" (box top, etc.)
 9) pixel count: below horizon
10) pixel count: below processing zenith
11) pixel count: mask
12) pixel count: unknown
13) pixel count: sky region 
- if shipboard mode:
        14) latitude
        15) longitude
        16) platform heading
- if circumsolar region defined:
        17) sun region total
        18) sun region opaque
        19) sun region thin
- if horizon region defined:
        20) horizon region total
        21) horizon region opaque
        22) horizon region thin
- if zenith region defined:
        23) zenith region total
        24) zenith region opaque
        25) zenith region thin
- if sun strength reporting enabled
        26) sun strength

Notes:

- Pixel count items 8 through 13 are mututally exclusive, i.e., they
  should add up to 288 x 352 = 101,376
        
- Item 26, sun strength is a ratio (expressed) of the pixel intensities 
  on the blocking band near the sun and farther away from the sun.  This
  value is not in any engineering units, and should be only interpreted as a 
  relative value.
