Abstract:
Introduction
The Moderate Resolution Imaging Spectroradiometer (MODIS) is one of the most
advanced sensors currently used for a wide range of land, ocean and atmosphere
applications. It has 36 spectral channels with spatial resolution varying from 250 m
to 1 km at nadir. The MODIS channels 1 (B1, VIS) and 2 (B2, near-infrared NIR,
0.85m) are available at 250 m spatial resolution. Five MODIS channels designed
for land applications (bands B3 to B7) are available at 500 m spatial resolution. The
remaining twenty nine channels are imaged at 1 km resolution.
For many applications, it is very desirable to have land channels at higher spatial
resolution. It has been shown that the optimal spatial resolution should be of the
order of few hundred meters for operational crop monitoring and other land
monitoring applications. The Fourier spatial analysis conducted by Trishchenko,
2004 for typical agricultural area showed that for the spatial sizes below 2 km, the
maximum in spatial spectra corresponds to spatial scales <100m, which describes
small scale spatial heterogeneity. There exist two maxima at the 200-300m and 400700m scales which describe the typical size of various land cover types. Clearly,
these features can be better resolved with spatial resolution of 250 m compared to
500 m or 1000 m. The high spatial resolution enables the monitoring of relatively
homogeneous land cover types and, therefore, allowing more accurate assessment
of the surface and biome properties. A spatial scale 250 m will be also useful for the
monitoring forest cover, mixed scenes, inland water bodies, forest fires, snow cover
and many other applications. The MODIS product produced at CCRS at 250 spatial
resolution addresses this need.

Process_Description:
The processing of the MODIS data at CCRS includes the following steps:
Step 1: Downscaling each MODIS/Terra 5-min granule consisting of MODIS
channels B3, B4, B5, B6, B7 at 500m spatial resolution into 250m
imagery using adaptive regression and radiometric normalization as
described by Trishchenko et al., 2006. This makes channels B3-B7
consistent in spatial resolution with 250m channels B1 and B2.
Step 2: Re-projection of all channels B1-B7 available now at 250 m spatial
resolution into LCC geographic projection using concurrent gradient
search method developed by Khlopenkov et al., 2006
Step 3: Running scene identification algorithm to produce a) mask of clear-sky,
cloudy and cloud shadow indices and b) Canada-wide clear-sky composite
image (region also includes part of US territory, Greenland, Iceland and
surrounding oceans)
