Observing The Mediterranean Sea from space: 21 years of Pathfinder-AVHRR Sea Surface Temperatures (1985 to 2005). Re-analysis and validation
نویسندگان
چکیده
The time series of satellite infrared AVHRR data from 1985 to 2005 has been used to produce a daily series of optimally interpolated SST maps over the regular grid of the operational MFSTEP OGCM model of the Mediterranean basin. A complete validation of this OISST (Optimally Interpolated Sea Surface Temperature) product with in situ measurements has been performed in order to exclude any possibility of spurious trends due to instrumental calibration errors/shifts or algorithms malfunctioning related to local geophysical factors. The validation showed that satellite OISST is able to reproduce in situ measurements with a mean bias of less than 0.1 K and RMSE of about 0.5 K and that errors do not drift with time or with the percent interpolation error.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Earth Observing System satellites Terra and Aqua include infrared bands that are designed for the accurate measurement of sea-surface temperature (SST). In addition to the conventional ‘split-window’ bands in the 10-12 μm atmospheric window (similar in spectral properties to the corresponding channels of the heritage instrume...

With recent, dramatic changes in Arctic sea ice and the Antarctic ice sheets, the importance of monitoring the climate of the polar regions has never been greater. While many individual global satellite products exist, the AVHRR Polar Pathfinder products provide a comprehensive set of variables that can be used to study trends and interactions within the Arctic and Antarctic climate systems. Th...
متن کاملEffect of sea surface temperature (SST) changes on coral ecosystems in Kish Island
Background and Theoretical Foundations: Coral reefs are one of the world's most attractive ecosystems. They have been covering large parts of the world in the tropic areas. Coral reefs in the Iranian waters of the Persian Gulf are largely limited to the Islands. Many factors, including natural and anthropogenic activities cause stress to the reef communities affecting reef development. Coral bl...
متن کاملCapabilities of data assimilation in correcting sea surface temperature in the Persian Gulf
Predicting the quality of water and air is a particular challenge for forecasting systems that support them. In order to represent the small-scale phenomena, a high-resolution model needs accurate capture of air and sea circulations, significant for forecasting environmental pollution. Data assimilation is one of the state of the art methods to be used for this purpose. Due to the importance of...
