Product Description

Climatology metrics: A climatology, by definition, is the long-term condition representing the expected temperature value or variation for a site. In addition to data and images of the Monthly Climatology of sea surface temperature (SST), metrics identify which of the 12 months is the climatologically warmest and coolest, as well as the typical range of SST experienced. Climatology values are determined at coral reef-containing and adjacent satellite pixel locations worldwide, for the period 1985-2012, using the Version 1.0 CoralTemp daily global 5km SST data product. (The 28-year climatology period for the Version 2.0 Thermal History products reflects Coral Reef Watch's established methodology for its Version 3.0 [and later] daily global 5km satellite coral bleaching heat stress products.)

Where relevant, the range of values calculated from analyzed pixels is shown in [brackets] after each metric name.

Warmest Month, Coolest Month, Climatological Range [0.3-16.0°C] and Monthly Climatology [12.6-34.3°C]: For each month, the average temperature is determined for each year in the climatology period 1985-2012, and the linear regression coefficients determined for each individual pixel. The Monthly Climatology is set to the regression solution at the time 1988.286, which is the time-center (temporal mid-point) of Coral Reef Watch's heritage 50km climatology and subsequent 5km climatologies (both current and historical)1. The Warmest and Coolest Months are identified from the Monthly Climatology, and the Climatological Range derived from those values.
