How does the SeaWiFS climatology and anomaly function work?
What are MODIS-Terra, MODIS-Aqua, and SeaWiFS? MODIS stands for the Moderate Resolution Imaging Spectroradiometer. There are two MODIS instruments in orbit; MODIS-Terra is on the Terra satellite, which observes the Earth (in daytime) during the morning. This should allow better surface observations due to reduced cloud cover. MODIS-Aqua is on the Aqua satellite, which observes the Earth (during the daytime) in the early afternoon. This timing allows for improved observations of clouds and other atmospheric variables, which other instruments on Aqua are intended to measure. SeaWiFS stands for the Sea-viewing Wide Field-of-view Sensor, an instrument which primarily observes the oceans, but also provides data and imagery from land. The two MODIS instruments have a large number of spectral bands allowing measurements of land, ocean, and atmospheric variables; SeaWiFS has only eight bands used for ocean observation and atmospheric correction.
