Here we provide sea surface temperature (SST) data retrieved from observations of the satellite microwave radiometer Advanced Microwave Scanning Radiometer an Bord EOS (AMSR-E). This data is part of a "Multi-Parameter-Product", which is routinely produced at Remote Sensing Systems (see references) using AMSR-E brightness temperatures. The advantage of using microwave data instead of infrared data is, that the weather influence (emission and attenuation by water vapour and clouds) can be neglected, particularly for the low-frequency AMSR-E channels (6.9 GHz and 10.7 GHz). Note that due to the finite penetration depth of microwave radiation into the water column the observes SST represents the temperature of the uppermost millimeter
The AMSR-E sensor offers a complete daily data coverage at high latitudes while a mid- and low latitudes quite a number of data gaps occur. Therefore we offer here 3-day composites. This data is essentially free of data gaps. This data set is the final version (version 07) of this product.
Note that due to the large field-of-view which is associated with the used frequencies, a proper SST retrieval is not possible along coasts (even of small islands) and along the ice edge. Therefore no data is available for an approximately 75 km wide region adjacent to coasts and the ice edge.
ATTENTION: Recent results published by Gentemann, C. L., 2014 (see references) suggest a bias in the SST due to an incorrect application of a correction factor for low water vapour contents. This required bias correction is described in as well in Gentemann, C. L.. (2014).
Last update of data set at ICDC:
|SST (sea surface temperature)||°C|
|Data flag (information about missing data)||-|
Period and temporal resolution:
- June 1, 2002 to Oct. 04, 2011
- Daily as 3-day composite (file name corresponds to last day of 3-day interval used)
- June 2002 to September 2011
Coverage and spatial resolution:
- Spatial resolution: 0.25° x 0.25°, cartesian grid
- Geographic latitude: -89.875°N to 89.875°N
- Geographic longitude: 0.125°E to 359.875°N
- Dimension: 1440 columns x 720 rows
- Altitude: 0.0 m
This SST data has been compared to buoy observations, ship-based observations and the Reynolds SST. The data set does not include separate uncertainty estimates or quality flags; it contains however in a separate layer information regarding the reason for missing data (e.g. due to sea ice).
We suggest to take a look at the respective REMSS webpage and the other documents under references given below for more information.
