The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Term: | MODIS |
| Description: | Moderate Resolution Imaging Spectroradiometer |
| Definition: | MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications).
MODIS Technical Specifications Orbit: 705 km, 10:30 a.m. descending node (Terra) or 1:30 p.m. ascending node (Aqua), sun-synchronous, near-polar, circular Scan Rate: 20.3 rpm, cross track Swath Dimensions: 2330 km (cross track) by 10 km (along track at nadir) Telescope: 17.78 cm diam. off-axis, afocal (collimated), with intermediate field stop Size: 1.0 x 1.6 x 1.0 m Weight: 228.7 kg Power: 162.5 W (single orbit average) Data Rate: 10.6 Mbps (peak daytime); 6.1 Mbps (orbital average) Quantization: 12 bits Spatial Resolution: 250 m (bands 1-2); 500 m (bands 3-7); 1000 m (bands 8-36) Design Life: 6 years (From: http://modis.gsfc.nasa.gov/about/index.html) |
