MODIS spectrometer

Ocean surface temperature AYHRR, ATSR-2/ERS-2, AATSR/ENYISAT, MODIS/ EOS-Terra/Aqua, AMSR-E/EOS-Aqua, OCTS/ADEOS. Spaceborne system EOS/Terra is equipped with radiometer ASTER to measure thermal radiation and its reflection from the ocean surface, spectrometers MODIS and MISRC, as well as MOPITT and CERES instruments to record pollutant and energy fluxes, respectively. 

Figure 2 Schematic representation of a triple quadrupole mass spectrometer. The principle of frequently used scan modi is indicated. Please note that MRM is based on monitoring multiple specific precursor/product ion pairs.

Table 3 Algorithms used to calculate chlorophyll a (C) from remote sensing reflectance. R is determined as the maximum of the values shown. Sensor algorithms are for Sea-viewing Wide Field of view Sensor (SeaWiFS), Ocean Color and Temperature Scanner (OCXS), Moderate Resolution Imaging Spectroradiometer (MODIS), Coastal Zone Color Scanner (CZCS), and Medium Resolution Imaging Spectrometer (MERIS).

The description of a gas chromatograph modi ed for the snif ng of its ef uent to determine volatile odor activity was rst published by Fuller et al. [63]. In general, GC-olfactometry (GC-0) is carried out on a standard GC that has been equipped with a snif ng port, also denominated olfactometry port or transfer line, in substitution of, or in addition to, the conventional detector. When a FID or a mass spectrometer is also used, the analytical column ef uent is split and transferred to the conventional detector and to the human nose. GC-0 was a breakthrough in analytical aroma research, enabling the differentiation of a multitude of volatiles, previously separated by GC, in odor active and nonodor active, related to their existing concentrations in the matrix under investi gation. Moreover, it is a unique analytical technique that associates the resolution power of capillary GC with the selectivity and sensitivity of the human nose.
