SeaWiFS (Sea-Viewing Wide Field-of-View Sensor) was a satellite-borne sensor designed to collect global ocean biological data. Active from September 1997 to December 2010, its primary mission was to quantify chlorophyll produced by marine phytoplankton (microscopic plants).
Data are archived in the SeaBASS repository from field campaigns throughout the world, similar to the distribution of the ocean data shown in this example map. The SeaWiFS Bio-optical Archive and Storage System (SeaBASS) is a data archive of in situ oceanographic data used to support satellite remote sensing research of ocean color .
Giovanni is a Web interface that allows users to analyze NASA's gridded data from various satellite and surface observations. Giovanni lets researchers examine data on atmospheric chemistry, atmospheric temperature, water vapor and clouds, atmospheric aerosols, precipitation, and ocean chlorophyll and surface temperature. The primary data ...
Places where chlorophyll concentrations are high, meaning many phytoplankton were growing, are yellow. The observations come from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite. Land is dark gray, and places where MODIS could not collect data because of sea ice, polar darkness, or clouds are light gray.
The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies. These are not necessarily in the public domain. Materials based on Hubble Space Telescope data may be copyrighted if they are not explicitly produced by the STScI. See also {{PD-Hubble}} and {{Cc-Hubble}}.
They capture data in 36 spectral bands ranging in wavelength from 0.4 μm to 14.4 μm and at varying spatial resolutions (2 bands at 250 m, 5 bands at 500 m and 29 bands at 1 km). Together the instruments image the entire Earth every 1 to 2 days.
It is one of the most frequently used models for primary production estimation due to its ability to be applied to chlorophyll a data from satellites, and its relatively simple design. [2] Chlorophyll a is a common measure of primary production, as it is a main component of photosynthesis. [1] [3] [2]
The PACE project is managed by NASA Goddard Space Flight Center. [7] The main instrument and bus were designed and built at Goddard Space Flight Center. [8] On 4 February 2020, NASA announced the selection of SpaceX to launch PACE on a Falcon 9, at a total cost to NASA of US$80.4 million, including the launch service and other mission-related ...
