definition A 14-day mosaic SST product, based on the IMOS L3S 1-day product, is also created within the ReefTemp Next Generation system. This product is created by filling any missing data pixels in today's SST data with the most recent available 1-day data from up to 14 days ago. The temperature range visualised is from 20–35°C.

The 14 day SST mosaic product was developed to mimic the legacy Bureau SST mosaic product that underpinned ReefTemp V1, to assist reef mangers to transition smoothly to the ReefTemp Next Generation system. It is important to note that whilst a more complete SST image is available using the 14 day mosaic method, it can be spatially inhomogeneous.

definition SSTA is the difference between SST values and climatology, the monthly long term mean SST. Two climatologies are used to produce products. The first is an IMOS climatology for 2002–2011, constructed for each month using IMOS L3S 1-day night-only SST products in that period. The second climatology used is the CSIRO 1993–2003 climatology that the ReefTemp V1 system utilised. The use of both climatologies allows for comparisons of products based on different reference periods. All SSTA values appear in the range -4°C to 4°C.

definition Degree Heating Days (DHD) are the accumulation of positive SSTA values over the summer (1 December  to 31 March ) at each grid cell. If no data is available, DHDs are not accumulated and remain the same as the previous day. The visualisation range for DHD values is 0–240 °C days. This product is only available between December and March inclusive.

definition Mean Positive Summer Anomaly (MPSA; formerly known as Heating Rate), calculated as the number of Degree Heating Days (DHD) divided by the Degree Heating Day Count (DHDC). The visualisation range for MPSA values is 0-5 °C. This product is only available between December and March inclusive.

definition Data Error Bias indicates the errors (deg C) in the input IMOS L3S 1-day night-only SST data at each pixel due to proximity to cloud, instrumentation errors and the like.

definition Data Quality Level (QL) indicates the quality level of the input IMOS L3S 1-day night-only SST data where 3 = low quality, 4 = acceptable quality and 5 = best quality. Quality levels are determined using the data error for each pixel.
