<p class="card_title">GCOM-C (Land and Ocean Products)</p>

<div>
<p>GCOM is seen as a follow-up programme to ADEOS-II (launched in December 2002) with the overall objective to contribute to global change research through long-term (&gt; 10 years) sustained observations with corresponding data sets. The JAXA Global Change Observation Mission (GCOM) consists of a constellation of two medium-sized spacecraft with the provisional names of GCOM-W (for WaterCycle studies) and GCOM-C (for Climate studies).</p>

<p>The GCOM-C satellites carry a Second Generation Global Imager (SGLI), an advanced multi-purpose imager with 19 spectral bands divided in two instruments: the Visible and Near InfraRed Radiometer (SGLI-VNR) and the Infrared Scanner (SGLI-IRS). The first satellite in this series, GCOM-C1, was successfully launched in December 2017.</p>

<p>Within the EDAP&nbsp;<a href="https://earth.esa.int/eogateway/activities/edap/atmospheric-missions" target="">Atmospheric Missions</a>&nbsp;domain, a quality assessment of the atmospheric aerosol products has been conducted, and within this Low Resolution domain, a quality assessment of the land and ocean products has been conducted.</p>

<p>MOS-1 was Japan's first EO spacecraft, operating in a sun-synchronous orbit with a repeat period of 17 days. It was launched in February 1987 and extended to November 1995, with MOS-1b following in February 1990 and ending in April 1996.</p>

<p>Both satellites carried the Multispectral Self-Scanning Radiometre (MESSR) with four wavebands (visible and near-infrared) at 50 m resolution and the Visible and Thermal Infrared Radiometre (VTIR) with one waveband in the visible, two in the thermal infrared and a water vapour absorption waveband at 900 m spatial resolution. There was also a passive Microwave Scanning Radiometre (MSR).</p>
