Thank you for your continued support of Tellus.

The quasi-real-time product and 8-day time statistic data of "sea surface water temperature", "chlorophyll-a concentration", and "suspended solids concentration" acquired by JAXA's Climate "SHIKISAI" (hereinafter, "GCOM-C") will be available free of charge on "Tellus Traveler" beginning June 23, 2022.

Data on "sea surface water temperature", "chlorophyll-a concentration" and "suspended solids concentration" are expected to be used to understand the effects of climate change on the oceans and also to be used for fisheries and other purposes. Archived data on "sea surface water temperature" and "chlorophyll-a concentration" have been available on "Tellus OS".

The new quasi-real-time product, which is available in as little as 70 minutes after the image is taken, and the time-statistics data, which are averages calculated by removing clouds and other elements from 8 days of observation data, will enable us to grasp the status of seawater in near real time.

JAXA has been providing quasi-real-time products to some researchers on a limited basis, and the Tellus will be the first site offered in an environment that can be viewed by the general public, including individuals.

<About Data>
【Sea Surface Water Temperature】
■Summary: This is the temperature data of the water surface at sea. By observing the temperature, it is possible to determine the conditions such as the boundaries (tides) between warm and cold currents.

【Chlorophyll-a Concentration】
■Summary Data on the concentration of chlorophyll-a, a photosynthetic pigment contained in phytoplankton and other organisms distributed on the sea surface.　 The higher the concentration, the more phytoplankton is distributed on the sea surface.

【About "GCOM-C"】 This Earth observation satellite was developed by JAXA and launched in 2017 to study the long-term effects of global warming and other climate changes. The Second generation GLobal Imager (SGLI) on GCOM-C is an optical sensor capable of multi-channel observation at wavelengths from near-UV to thermal infrared wavelengths (380nm to 12µm.) to observe clouds, aerosols (dust in the atmosphere), ocean color, vegetation, snow and ice, and more. Observed data is provided by JAXA's website "G-Portal" and other sources.
