What are the components of the MODIS LST product?
The product is comprised of LSTs, quality assessment, observation time, view angles, and emissivities. Radiance-based validation and comparisons performed in 2008 with AIRS and ASTER products indicate that the land surface temperature in the C5 CMG products underestimated LST by up to 6K in some desert regions.
Which is better the C4 MODIS or the C5 LST?
Subsequent to these findings, users requested continued production of the C4 MODIS LST products simultaneous with the C5 LST production in the belief that the C4 MODIS LST products provide better results over desert regions. It was thus decided at the 2008 science team meeting that both C4 and C5 LST would be produced and released to the public.
Which is MODIS dataset does Earth Engine use?
The MOD14A1 V6 dataset provides daily fire mask composites at 1km resolution derived from the MODIS 4- and 11-micrometer radiances.
How is the reflectance of MODIS data calculated?
The MCD43A4 V6 Nadir Bidirectional Reflectance Distribution Function Adjusted Reflectance (NBAR) product provides 500 meter reflectance data of the MODIS “land” bands 1-7. These are adjusted using a bidirectional reflectance distribution function to model the values as if they were collected from a nadir view.
Where can I find the MODIS land product validation?
Further details regarding MODIS land product validation for the LST/E products are available from the following URL: http://landval.gsfc.nasa.gov/ProductStatus.php?ProductID=MOD11. Zhengming Wan – University of California Santa Barbara, Simon Hook, Glynn Hulley – JPL and MODAPS SIPS – NASA. (2015).
How is MODIS / terra land surface temperature / emissivity valid?
Collection-5 MODIS/Terra Land Surface Temperature/Emissivity products are validated to Stage 2, which means that their accuracy has been assessed over a widely distributed set of locations and time periods via several ground-truth and validation efforts.
