description: ADEOS OCTS L2 GAC OC1 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.Â This product is GAC (Global Area Coverage) ocean color1 (OC1) product, transformed to geophysical parameters from level 1B data, includes Normalized water-leaving radiance at 412, 443, 490, 520, 565 nm, Aerosol radiance at 670, 765, 865 nm, Epsilon of aerosol correction at 670 and 865 nm and Aerosol optical thickness at 865 nm data. Furthermore, supplemental data, such as geometric correction information, the OCTS telemetry, quality information, the sun vector, scene information and others are included.The provided format is HDF4 format The Spatial resolution is 700 m.
