Geoscience Australia, ACRES has released the first Moderate Resolution Imaging Spectroradiometer (MODIS) Surface Reflectance product. The Surface Reflectance product provides satellite imagery which represents an estimate of land surface spectral reflectance as it would be measured at ground level in the absence of atmospheric absorption and scattering.
The new product offers researchers and scientists a capability to more precisely observe the Earth in the visible and infrared regions of the spectrum and view the Earth's surface every day with spatial resolutions at 250m, 500m and 1000m.
The Surface Reflectance product is part of a new suite of online products which include calibrated and geolocated at-aperture radiance Level 1B map oriented GEOTIFF format products. The Surface Reflectance product is the result of significant steps made by ACRES operations in the implementation of the MODIS Surface Reflectance algorithm (MOD09).
The new Surface Reflectance and Level 1B products are the results of a change to SeaDAS MODISL1DB (SeaWiFS Data Analysis System) processing software. The new products offer improved quality and interoperability with image processing packages and tools.
Although this new product range is currently available only for our online products (ie pre-processed products from data acquired in the last 7 days), we intend to extend the new product range to archive data processing within the next month.
Free online imagery covering the Australian landmass, most of Papua New Guinea, Eastern Indonesia and New Zealand is available on our website.

Images from CBERS can provide valuable information to land managers and policy makers about the nature of Australia's land surface, specifically in areas such as environmental monitoring, agriculture, mapping and emergency management...[full story].
This is the first image acquired by GA from CBERS on 7th April 2006. Image is approximately 100km east of Alice Springs, Northern Territory, Australia. The swath width is around 110km (Click graphic for high-resolution image).

On the 2nd April 2006 Landsat 5 resumed transmission after an uncommanded shutdown on 15th March 2006. Reliable operations are expected for the foreseeable future. For more information visit the USGS website.
