Multi-Spectral Clear-Sky Composites of MODIS/Terra Land Channels (B1 - B7) Over Canada at 250m Spatial Resolution, 2000-03-01 to 2013-01-10

The Moderate Resolution Imaging Spectroradiometer (MODIS ) is one of the most sophisticated sensors that is used in a wide range of applications related to land, ocean and atmosphere. It has 36 spectral channels with spatial resolution varying between 250 m and 1 km at nadir. MODIS channels 1 (B1, visible) and 2 (B2, near infrared) are available at 250 m spatial resolution, an additional five channels for terrestrial applications (bands B3 to B7) are available at 500 m spatial resolution, the other twenty-nine channels not included in this data set capture images with a spatial resolution of 1 km. The MODIS record begins in March 2000 and extends to present with daily measurements over the globe. This level 3 product for Canada was created from the following original Level 1 (1B) MODIS data (collection 5): a) MOD02QKM - Level 1B 250 m swath data, 5 min granules; b ) MOD02HKM - level 1B , 500 m swath data, 5 min granules; c) MOD03 - level 1 geolocation information, 1 km swath data, 5 min granules. All these data are available from the DAAC Earth Observing System Data Gateway (NASA http://ladsweb.nascom.nasa.gov/data/search.html ). The terrestrial channels MODIS (B3 to B7) at 500 m spatial resolution were reduced to 250 m with an adaptive regression system and normalization described in Trishchenko et al. (2006, 2009), and the data were mapped using a Lambert Conformal Conic (LCC ) projection (Khlopenkov et al., 2008). These data were combined to form pan-Canadian images using a technique for detection of clear sky, clouds and cloud shadows with a maximum interval of 10 days (Luo et al., 2008). Atmospheric and sun-sensor geometry corrections have not been applied. For each date, data include forward and backward scattering observations as separate files. This allows data to be optimized for a given application. For general use, data from either forward or backward scattering or both should be used. Future release of the MODIS time series will correct the forward and backward scattering geometry to provide a single best observation for each pixel.

Multi-Spectral Clear-Sky Composites of MODIS/Terra Land Channels (B1-B7) Over Canada at 250m Spatial Resolution and 10-Day Intervals Since March, 2000: Top of the Atmosphere (TOA) Data
Issue identification
2014
Purpose
These data provide measurements of top-of-atmosphere reflectance of the land surface that can be used to study processes and trends at local to national scales. The high temporal resolution of the dataset allows evaluation of seasonality and phenology on intra-annual and interannual time scales. The length of the record provides the means to monitor changes in land surface conditions over time. These data can be used for retrievals of albedo, leaf area, land cover, land cover change, snow and lake ice cover, and spring leaf-out among others. Derived parameters are often used in ecosystem process models to study air quality/pollution impact, ground water storage, climate change, crop yield, and biochemical cycling.
