Source: NOAA Coral Reef Watch Operational Near-real-time Daily Global 5 km
Satellite Coral Bleaching Heat Stress Monitoring Product Suite since 1985.

Actions: Historical data were provided to NCEI on a STAR ftp server;
operational data were uploaded by STAR to the NOAA Production Distribution
and Access (PDA) system.  NCEI downloaded the data and cryptographic hash
digest fixity information files from one or both of these services. The
data files were then validated against the cryptographic hash digest
fixity information. An archival information package (NCEI Accession) was generated 
and the netCDF and PNG files were copied to the data/0-data/ directory. A sample
browse graphic for one of the 5km Coral Bleaching Heat Stress Monitoring
products provided by the producer was copied to the about/ directory.

Files:

about/ 
This directory contains files created by NCEI staff, including 'negotiable'
information between NCEI staff and the data provider.

data/0-data/
This directory contains the data files as submitted to NCEI, including both
graphics and NetCDF data files. The sub-directories structure is:
/data/0-data/5km/v3.1/nc/    - where all .nc files reside
/data/0-data/5km/v3.1/image_plain/  - where all low resolution png files reside
/data/0-data/5km/v3.1/image_browse/   - where all medium resolution graphic png files reside

1. netCDF data files:
CoralTemp daily files: coraltemp_[version]_[YYYYMMDD].nc
coraltemp = CoralTemp 5km Sea Surface Temperature dataset
Version = The version of the CRW 5km CoralTemp product suite represented in the file
YYYYMMDD = four-digit year, 2-digit month, 2-digit day relevant to data in file

Daily files: ct5km_[datatype]_[version]_[YYYYMMDD].nc
ct5km = Coral Temp 5km SST, the SST analysis that this product suite is based on
datatype = baa, dhw, hs, ssta, baa-max-7d, sst-trend-7d 

  baa = Bleaching Alert Area
  dhw = Degree Heating Week
  hs = Hot Spot
  ssta = Sea Surface Temperature Anomaly
  sst-trend = Sea Surface Temperature Trend (based on availability from the Coral Reef Watch website at the time of archival)

Version = The version of the CRW 5km heat stress product suite represented in the file
YYYYMMDD = four-digit year, 2-digit month, 2-digit day relevant to data in file

Monthly Composite files: ct5km_[datatype]_[version]_[YYYYMM].nc
ct5km = Coral Temp 5km SST, the SST analysis that this product suite is based on
datatype = baa-max, dhw-max, hs-max, sst-max, sst-min, sst-mean, ssta-max, ssta-min, ssta-mean

  baa = Bleaching Alert Area
  dhw = Degree Heating Week
  hs = Hot Spot
  sst = Sea Surface Temperature
  ssta = Sea Surface Temperature Anomaly

Version = The version of the CRW 5km heat stress product suite represented in the file
YYYYMM = four-digit year, 2-digit month

2. PNG image files:
Each .nc file has 2 corresponding .png files, a coarse resolution and high resolution version of the
same image. e.g.,

CoralTemp Daily files:
   * coraltemp_[version]_[YYYYMMDD].png
   * coraltemp_[version]_global_[YYYYMMDD].png

coraltemp = CoralTemp 5km Sea Surface Temperature dataset
Version = The version of the CRW 5km CoralTemp product suite represented in the file
YYYYMMDD = four-digit year, 2-digit month, 2-digit day relevant to data in file
