AbstractThe Visible Infrared Imaging Radiometer Suite (VIIRS) represents a new generation of satellite imagers for global operational observations. In many aspects, it is comparable to the Moderate Resolution Imaging Spectroradiometer (MODIS) operated since 2000, i.e. almost for two decades. The Canada Centre for Remote Sensing has developed a unique MODIS processing chain to produce a long-term time series of clear-sky composites and some terrestrial products at 250 m spatial resolution over a 5700 km × 4800 km region centered on Canada. The paper describes an extension of the MODIS time series at the top of the atmosphere level using VIIRS data. The VIIRS clear-sky composites are produced on a 250-m spatial grid for I-bands and a 500-m grid for M-bands. Nominal products are generated as 10-day composites, while snow mask and normalized difference vegetation index are generated as daily products. Preliminary assessment of VIIRS versus MODIS composites has been conducted through comparison of value-added warm season snow/ice probability maps and minimum snow/ice extent. The results demonstrate a high level of consistency (with the average different difference around 0.12%), which indicates that the developed VIIRS processing technology produces results that can potentially be used to extend MODIS time series into the future.

The Visible Infrared Imaging Radiometer Suite represents a new generation of satellite imagers. In many aspects, the VIIRS is comparable to the Moderate Resolution Imaging Spectroradiometer operated in space since 2000. The Canada Centre for Remote Sensing has developed a unique MODIS processing chain to produce a long-term time series of clear-sky composites and some terrestrial products at 250-m spatial resolution over Canada. The paper describes an extension of the MODIS time series using VIIRS data. The VIIRS products are generated on 250-m spatial and 500-m grid. Nominal products are generated as 10-day composites, while snow mask and normalized difference vegetation index are generated daily. Preliminary assessment has been conducted through comparison of snow/ice probability maps and extent. The results demonstrate a high level of consistency, which indicates that the developed VIIRS processing technology can be used to extend MODIS time series into the future.
