USA – December 12th, 2012

Although clouds hang over the southern part of the state of Louisiana and the northern part of the Gulf of Mexico, the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature lets users see the Louisiana shoreline, including the Mississippi River Delta. The feature allows users to download images with countries’ outlines superimposed over cloudcover.

Fires in Queensland, Australia and Area of Convection Over Gulf of Carpentaria – December 12th, 2012

Australia – December 12th, 2012

Fires in Queensland, Australia, just south of the base of the Cape York Peninsula and southeast of the Gulf of Carpentaria, release plumes of smoke that blow in a slightly curved shape towards the south-southwest.

Also visible here is the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature, which allows users to download images with countries’ outlines superimposed over cloudcover. Although an area of convection hangs over the southeastern shores of the Gulf of Carpentaria, the Queensland shoreline can be seen thanks to this feature.

Typhoon Bopha (26W) Over Palawan Island, Philippines – December 7th, 2012

Track of TY 26W

Typhoon Bopha (TY 26W) is located approximately 320 nautical miles west of Manila, Philippines. The system has tracked north-northwestward at 08 knots over the past six hours. Maximum significant wave height is 20 feet.

Also visible in these images is the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature, which allows users to download images with countries’ outlines superimposed over cloudcover. Although the typhoon obscures the land and sea below it, thanks to this feature, the outline of Palawan Island can be seen directly below the center of the storm (best observed upon opening full image).

Palawan Island is the largest island of the Palawan Province, Philippines. The northern coast of the island is along the South China Sea, while the southern coast forms part of the northern limit of the Sulu Sea. This island has abundant wildlife, jungle mountains, and white sandy beaches.

SRRS Participating in GMES Masters Competition – Thank you to all who voted!

GMES Master Competition - Best Service Challenge

In emergency situations it is necessary to provide a response as quickly as possible. When the type of emergency depends on the use of satellite data, it then becomes necessary to plan their acquisition, processing and distribution, having teams ready 24 hours per day, 7 days a week, to respond to this type of situation.

The Satellite Rapid Response System was created by CHELYS precisely with the intent of making satellite data available as quickly as possible, as images and value-added products.

The constellation of satellites known as GMES (Global Monitoring for Environment and Security) that will be launched starting in 2013, thanks to low revisiting times and the planning of the whole mission already present on board the satellite, will allow monitoring of our planet as never seen before.

SRRS is participating in the GMES Masters Competition in the Best Service Challenge. You can visit SRRS at the following link:

If you consider this type of service useful, if you like it, if you would like to continue using it with new data that will be made available by GMES, then vote for the service at the following link:

It is also important to note that although SRRS is participating in the Emergency Response category, it actually has a much wider range of applications, such as Ocean, Land or Climate Change.

If you have any thoughts regarding the service or ideas on ways to improve it, please leave us a comment.

New FAPAR/MGVI Raw Data Processor for Monitoring Vegetation Cover

Envisat’s Medium Resolution Imaging Spectrometer (MERIS) acquires multi-spectral imagery of the Earth, and is used to monitor the state and evolution of the terrestrial vegetation cover.

In particular, the MERIS Global Vegetation Index (MGVI), which corresponds to the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), is generated operationally as a standard level-2 product, using the radiation measured by MERIS over land surfaces.

This bio-geophysical product plays a critical role in the plant photosynthetic process and is regularly used in diagnostic and predictive models to compute the primary productivity of the vegetation canopies.

FAPAR has been established as a fundamental surface parameter by international organizations including the Global Climate Observing System (GCOS), charged with providing data on the Earth’s climate system.

Chelys has developed a new processor that is able to process and directly extract the FAPAR index from raw data (level-0) at a reduced or full resolution (but also from level-1), generating the relative false-colored image just a few seconds after the original data is ingested.

In the next few weeks, a processor that will systematically generate these vegetation index images will be incorporated in the SRRS (Satellite Rapid Response System). As soon as enough images have been collected, it will be possible to generate mosaics as well.
