analysis of sea surface current in sea surface temperature images
oceanographic images obtained from environmental satellites by a wide range of sensors allow characterizing natural phenomena through different physical measurements. for instance sea surface temperature (sst) images, altimetry data and ocean color data can be used for characterizing currents and vortex structures in the ocean. the purpose of this thesis is to derive a relatively complete frame...
متن کاملAccuracy Assessment of Sea Surface Temperature from NOAA/AVHRR Data in the Seas around Korea and Error Characteristics
Sea Surface Temperatures (SSTs) using the equations of NOAA (National Oceanic and Atmospheric Administration) / NESDIS (National Environmental Satellite, Data, and Information Service) were validated over the seas around Korea with satellite-tracked drifter data. A total 1,070 of matchups between satellite data and drifter data were acquired for the period of 2009. The mean rms errors of MultiC...
متن کاملSimultaneous Tuning of Water Vapour and Atmospheric Temperature for Determination of Sea Surface Temperature from AVHRR
A novel physics-based method for determination of sea surface temperature (SST) from AVHRR is explained in detail. Starting from the equation of radiative transfer in the mean value approximation, we use variational calculus to derive an expression relating the difference between the radiance calculated using a first guess atmospheric profile and the observed satellite radiance (∆I), to the cor...
متن کاملSea surface temperature variability: patterns and mechanisms.
Patterns of sea surface temperature (SST) variability on interannual and longer timescales result from a combination of atmospheric and oceanic processes. These SST anomaly patterns may be due to intrinsic modes of atmospheric circulation variability that imprint themselves upon the SST field mainly via surface energy fluxes. Examples include SST fluctuations in the Southern Ocean associated wi...
متن کاملCoastal sea surface temperature variability from Landsat infrared data
A time series of 23 Landsat Thematic Mapper (TM) band 6 thermal infrared images over the period 1986–1996 is used to quantify variability of sea surface temperature (SST) along the central coast of Maine, a morphologically complex region of bays, estuaries, and islands. An iterative regression scheme using coregistered, temporally coincident, daily composites of Advanced Very High Resolution Ra...
