GOES-R Sea Surface Temperature
Frequently Asked Questions about the GOES-R Sea Surface Temperature Product
1) What is this product?
The GOES-R Sea Surface Temperature product produces SST values in degrees Kevin (which is converted to Celcius locally on AWIPS) for all pixels containing ocean that are not obscured by clouds. The SST product's horizontal resolution is 2km. The GOES-R SST product is created both day and night. It is accurate to within 3.1 degrees Kevin, and has a range of 271 - 313 K (-2 K to 40 C). The GOES-R SST product data is quantitative out to 67 degrees local zenith angle, and can be consdered qualatative beyond that.1
This product is useful when trying to assess the location of relatively warm or cold areas of ocean water, including ocean currents (such as the Gulf Stream).
2) How often do I receive this data?
The cadence of the GOES-R Total Precipitable Water product is every 60 minutes, regardless of scan mode. The image will always be a full disk image.
3) How do I display this product in AWIPS-II?
To display this product in AWIPS-II, go to the "GOES-R" tab of the CAVE menu, then select "Derived Products." From there, select the region of interest (GOES-E, GOES-W, or GOES Test) and then select Full Disk. Then, select the Sea Surface Temperature product.
Alternately, use the AWIPS Product Browser. Select "Sat", then either "GOES-16" or "GOES-17". From there, choose "Full Disk", then select "SST."
4) How do I interpret the color maps associated with this product?
Darker colors imply areas of relatively cold sea surface temperature, while brighter colors imply areas of relatively warm sea surface temperature
5) What other imagery/products might I use in conjunction with this product?
The GOES-R STT product can be used in conjunction with the similar products from polar satellites for comparison to actual observed sea surface temperatures.
6) How is this product created?
The GOES-R Sea Surface Temperature product is only calculated on pixels that are determined to be either "clear" or "probably clear" by the GOES-R Cloud Mask algorithm. It utilizes GOES-R bands 3.9 um, 8.5 um, 10.33 um, 11.2 um, and 12.3 um channels.
The ancillary data used to calculate the sea surface temperature includes1:
- GOES-R Cloud Mask product
- GOS-R Snow Cover product
- Land/sea coast mask
- Sea surface temperature reference field (Reynolds SST data (1 deg weekly or 0.25 deg daily) interpolated to the satellite grid
- Radiative transfer model clear sky brightness temperatures and Jacobian for GOES-R bands 3.9 um, 8.5 um, 10.33 um, 11.2 um, and 12.3 um channels. This data is 1 degree by 3, 6, 9, and 12 hours corresponding to input GFS data resolution interpolated to the satellite grid.1
