The NOAA Coral Reef Watch (CRW) daily global 5km 7-day Sea Surface Temperature
(SST) Trend product, updated daily, provides information on the pace and direction
of the SST variation, and thus coral bleaching heat stress, if present, over the
past seven days. Seven daily global 5km SST measurements, based on CRW's
Version 3.1 daily global 5km 'CoralTemp' SST product,
are included in the calculation used to derive the above product images. Pixels
colored in green have insignificant trends; this is due either to small SST trends
(within the range -0.2 to 0.2 °C) or trends that failed the two-tailed Student's-t
test for the 20% significance level with five degrees of freedom.
This product is updated each afternoon at about 13:30 U.S. Eastern Time.
