Science Data Sets provided in the MCD15A2H include LAI, FPAR, a quality assurance rating, and standard deviation for each variable The temporal resolution of MODIS data (period between two consecutive observations) for this study varied widely and reached 15 days for 8-day composites and 30 days for 16-day composites. Due to maize leaf area inde MODIS/Terra Snow Cover 8-Day L3 Global 500m SIN Grid, Version 6. This data set reports the maximum snow cover extent during an eight-day period in 1200 km x 1200 km tiles. Tiles are generated by compositing 500 m observations from the MODIS/Terra Snow Cover Daily L3 Global 500m Grid (MOD10A1) data set. Bit flags are also provided that report the. MODIS Reflectances (MR) global compositing period, 8 days. The spatial resolution will be constrained by the MODIS reflectance dataset, and may be as fine as 250m, or standardized to 1km.

. The MOD11C3 product which is delivered monthly has larger spatial resolution than MOD11A2. OR anyone has created a script. The MODIS snow algorithm output (MOD10_L2 and MYD10_L2) contains scientific data sets (SDS) of snow cover, quality assurance (QA) SDSs, latitude and longitude SDSs, local attributes and global attributes. The snow cover algorithm identifies snow-covered land; it also identifies snow-covered ice on inland water The MOD16A3GF will be generated at the end of each year when the entire yearly 8-day MOD15A2H is available. Hence, the gap-filled MOD16A3GF is the improved MOD16, which has cleaned the poor-quality inputs from yearl However, this product only has bands 1 and 2, as the rest of the MODIS bands are not high enough resolution to be released in this product. For surface reflection, there are also averages that are collected over 8 days, such as
Phytoplankton contain a photosynthetic pigment called chlorophyll that lends them a greenish color. When phytoplankton grow in large numbers they make the ocean appear greenish. These maps made from satellite observations show where and how much phytoplankton were growing on a given day, or over a span of days Improvements/Changes from Previous Versions. The 16-day composite VI is generated using the two 8-day composite surface reflectance granules ( MOD09A1) in the 16-day period. This surface reflectance input is based on the minimum blue compositing approach used to generate the 8-day surface reflectance product MOD16A2 gives you the 8-day composite. The period of coverage is 8 days with the exception of the last period at the end of the year which is either 5 or 6 days. For eg: ET/PET units are 0.1mm/5.

Show activity on this post. I am using the MODIS MOD16A2 Evapotranspiration data set which comes as a 500x500 meter grid of the 8 day sum of evapotranspiration. The first file ends in _001 which means that it starts on January 1st and goes until the 8th. The next file, _009, then covers the 8th to the 16th of January and on and on temporal frequencies are 1 and 8 days. Upstream Product Requirements The FPAR, LAI algorithm requires the MODIS inputs, representing the outputs of various upstream data processing phases. Table 1.
