**Data Description:**
####################
The California satellite dataset using the MODerate-resolution Imaging Spectroradiometer (MODIS) product MCD43A4 provides reflectance data adjusted using a bidirectional reflectance distribution function (BRDF) to model the values as if they were taken from nadir view.
Both Terra and Aqua data are used in the generation of this product, providing the highest probability for
quality input data.

**Data Organization:**
####################
The nine data folders correspond to three years of data.Under this top level directory structure are separate files for each band (1 - 7) and each 8-day period of the particular year. Within the period the best observations were selected for each location.
**File Naming Conventions:**
###########################
Each of the files represent a 2D dataset with the naming conventions as follows:
MCD43A4.CA_1KM.005.. .flt32
where
is the beginning year-day of the period that where YYYY = year and DDD = day of year (001 - 366)
represents the observations in particular (spectral) band (band 1 - band 7) - since the indexing is 0-based,
the range of indexes on the files is from 0 - 6 (where 0 = band 1, and 6 = band 7)
The spectral band frequencies for the MODIS acquisitions are as follows:
BAND1 620 - 670 nm
BAND2 841 - 876 nm
BAND3 459 - 479 nm
BAND4 545 - 565 nm
BAND5 1230 - 1250 nm
BAND6 1628 - 1652 nm
BAND7 2105 - 2155 nm
