MODIS/Aqua Atmospherically Corrected Surface Reflectance 5-Min L2 Swath 250m, 500m, and 1km
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/modis/myd09.061
The Aqua MODIS (Moderate Resolution Imaging Spectroradiometer) Surface Reflectance products provide an estimate of the surface spectral reflectance parameter as if it were measured at ground level in the absence of atmospheric scattering or absorption.
Description
The MODIS Level 1B (L1B) top-of-atmosphere calibrated instrument data are corrected for atmospheric gases and aerosols to produce this Level 2 (L2) product. These L2 inputs are used to generate higher-level gridded products.
MYD09 is the product short name for the L2 orbital swath-based atmospherically corrected surface reflectance product, generated daily at 250-meter, 500-meter and 1-kilometer resolutions. MYD09 contains 5-minute datasets for every 24-hour cycle that yields 288 granules. ##### Spectral Band Coverage MYD09 offers surface reflectance values for the following resolutions and bands:

- 250-meter resolution: Bands 1 and 2
- 500-meter resolution: Bands 1 – 7
- 1-kilometer resolution: Bands 1 – 16 and Band 26 This product also contains multi-resolution Quality Assurance (QA) layers, and 1-kilometer observation statistics besides solar-zenith and view-zenith angles. ##### Product Validation and Data Record The version 6.1 (v6.1) surface reflectance products are validated to Stage 3, meaning that the uncertainties in this product are well-quantified through comparison with both in situ (ground-based) measurements and other reference data. These uncertainties are characterized in a statistically rigorous manner over multiple global locations and time periods. The spatial and temporal consistency of this product has also been evaluated over a set of globally representative locations and time periods. The v6.1 MYD09 collection’s data record starts from July 4, 2002 (2002–185). ##### Science Data Sets The L2 MYD09 product, in Hierarchical Data Format (HDF4), contains the following Science Data Sets (SDS): 1. 250m_Surface_Reflectance_Band_1 2. 250m_Surface_Reflectance_Band_2 3. 250m_Reflectance_Band_Quality 4. 500m_Surface_Reflectance_Band_1 5. 500m_Surface_Reflectance_Band_2 6. 500m_Surface_Reflectance_Band_3 7. 500m_Surface_Reflectance_Band_4 8. 500m_Surface_Reflectance_Band_5 9. 500m_Surface_Reflectance_Band_6 10. 500m_Surface_Reflectance_Band_7 11. 500m_Reflectance_Band_Quality 12. 1km_Surface_Reflectance_Band_1 13. 1km_Surface_Reflectance_Band_2 14. 1km_Surface_Reflectance_Band_3 15. 1km_Surface_Reflectance_Band_4 16. 1km_Surface_Reflectance_Band_5 17. 1km_Surface_Reflectance_Band_6 18. 1km_Surface_Reflectance_Band_7 19. 1km_Surface_Reflectance_Band_8 20. 1km_Surface_Reflectance_Band_9 21. 1km_Surface_Reflectance_Band_10 22. 1km_Surface_Reflectance_Band_11 23. 1km_Surface_Reflectance_Band_12 24. 1km_Surface_Reflectance_Band_13 25. 1km_Surface_Reflectance_Band_14 26. 1km_Surface_Reflectance_Band_15 27. 1km_Surface_Reflectance_Band_16 28. 1km_Surface_Reflectance_Band_26 29. 1km_b16_Reflectance_Band_Quality 30. 1km_b8-15_Reflectance_Band_Quality 31. 1km_Band_3_Path_Radiance 32. 1km_Reflectance_Band_Quality 33. 1km_Reflectance_Data_State_QA 34. 1km_water_vapor 35. 1km_Atmospheric_Optical_Depth_Band_1 36. 1km_Atmospheric_Optical_Depth_Band_3 37. 1km_Atmospheric_Optical_Depth_Band_8 38. 1km_Atmospheric_Optical_Depth_Band_CM 39. 1km_Atmospheric_Optical_Depth_Band_QA 40. 1km_Atmospheric_Optical_Depth_Model 41.
