The image to the right is a false-color combination of Bands 2, 2, 1 from MYD09GQ, showing a portion of Tile h22v10 over northern Madagascar acquired January 31, 2007.

• Reduced number of data products:� MYD09GST, MYD09GHK, MYDMGGAD, MYDPT1KD, MYDPTHKM encapsulated within MYD09GA
• Revised methodology for choosing first layer observation
• Reduced file volume:� internal compression

Product Description
The MODIS Surface Reflectance products provide an estimate of the surface spectral reflectance as it would be measured at ground level in the absence of atmospheric scattering or absorption.� Low-level data are corrected for atmospheric gases and aerosols, yielding a level-2 basis for several higher-order gridded level-2 (L2G) and level-3 products.

MYD09GQ provides Band 1 and 2 at 250-meter resolution in a daily gridded L2G product in the Sinusoidal projection.� Science Data Sets provided for this product include reflectance for Bands 1 and 2, a quality rating, observation coverage, and observation number. ��This product is meant to be used in conjunction with the MYD09GA where important quality and viewing geometry information is stored.

Version-5 MODIS/Aqua Surface Reflectance products are validated, meaning that product uncertainties are well defined over a range of representative conditions. Although there may be later improved versions, these data are ready for use in scientific publications.
