Product Summary

ADEOS OCTS L3M RTC OCK dataset is obtained from OCTS sensor onboard ADEOS and produced by NASDA (National Space Development Agency of Japan). Advanced Earth Observing Satellite (ADEOS) is sun-synchronous quasi-recurrent orbiter launched on August 17, 1996, and carries OCTS (Ocean Color and Temperature Scanner) and AVNIR (Advanced Visible and Near-Infrared Radiometer) sensor.
The main objectives of ADEOS (MIDORI) is to contribute to elucidation of phenomena of the earth system through integrated observation of geophysical parameters using a number of sensors. ADEOS operation on orbit was given up on June 30, 1997, because the generated power was lost due to the accident of the blanket of the solar array paddle breaking.
OCTS observes the amount of chlorophyll and various substances contained in the sea, sea surface temperature, cloud formation process, etc by receiving 12 bands of wavelengths from the visible light region to the thermal infrared region. The observation field of OCTS is about 1400km, and it is possible to scan in the north-south direction. Those sensors aim at collecting global data for mainly understanding the state of the ocean and its phenomena.
This product is L3M, Level 3 map RTC (Real Time Coverage) Ocean Color-CZCS like pigment concentration (OCP) product. Level 3 Map data are LAC or RTC data generated from Level 2 or Level 1B LAC or RTC products and RTC products are available only for pigment concentration, chlorophyll concentration, diffuse attenuation coefficient and sea surface temperature. These parameters are map data and palette data of CZCS-like Pigment Concentration.
The provided format if HDF4 format. The unit of geophysical quantity in this product is "mg m-3".
