Very High Resolution Radiometer

The Advanced-Very-High-Resolution Radiometer (AVHRR) carried on board the NOAA-7 satellite has been collecting radiance data from the earth s surface since 1978. The polar-orbiting satellite records global data on a neardaily basis. The 4-kilometer data have been remapped by NO A A into monthly composites. The data are collected in 2 bands-one visible (VIS), the other near infrared (NIR). The Normalized Difference Vegetation Index, or NDVI, defined...

Under the conditions of the reduction of regional hydrographic measurements and surveys on the entire sea scale, the study of the interannual SST variability may be based only on the regular and permanently replenished information with a high spatio-temporal resolution. Such satellite information about the SST is acquired by the measurements with Advanced Very High Resolution Radiometers (AVHRR) onboard the satellites of the National Oceanic and Atmospheric Administration (NOAA). The efficiency of the use of these satellite data for the studies of the spatio-temporal variability of the Black Sea temperature regime was demonstrated in [8-13]. 

This chapter summarizes investigations on satellite-derived sea surface temperature (SST) of the Baltic Sea for the period 1990-2005. The sea surface temperature derived from the Advanced Very High Resolution Radiometer (AVHRR) of the National Oceanic and Atmospheric Administration (NOAA) weather satellites were used in the Baltic Sea research for the investigation of the temperature development, for detailed process studies, and monitoring purposes. 

This investigation is based on data of the Advanced Very High Resolution Radiometer operated on the weather satellite series of the National Oceanic and Atmospheric Administration of the United States of America. The first instrument was launched in 1978. Three versions of the multichannel scanning radiometer were operated at 13 satellites and measured in 5-6 channels in the visible, near-infrared and thermal infrared spectral range, as defined in Table 9.1.

Advanced Very High Resolution Radiometer (AVHRR) satellite imagery shows an enhanced aerosol optical depth in the Northern versus Southern Hemisphere (SH), with maxima in the vicinity of industrial regions (Durkee et al., 1991). In addition, the Stratospheric Aerosol and Gas Experiment (SAGE) data show a factor of 3 springtime and summertime enhancement of aerosol extinction in the NH midlatitude upper troposphere versus the SH (Kent et al., 1991). As noted in Chapter 2, most anthropogenic sulfate is produced in the NH.

Administration/National Aeronautics and Space Administration (NOAA/NAS A) Advanced Very High Resolution Radiometers (AVHRR) sea surface temperature data are being used to evaluate far-field plume simulations. 

Since the 1990 s, AVHRR (advanced very high resolution radiometer) satellites have provided low spatial resolution data on sea-surface temperature, volcanic cloud drift, and floods, among other meteorological and natural phenomena. The MODfS and the geostationary Meteosat satellites support similar applications. 

A number of scanning radiometers, based on this principle, have flown in low Earth orbits for meteorological purposes. Typical instruments are the two-chaimel radiometer of ITOS (1970) (Fig. 5.4.4) and the Very High Resolution Radiometer (VHRR) flown first on NOAA 2 in 1972. A more complete listing and several schematics of such instmments can be found in Houghton et al. (1984).
