Paper Abstract
This paper describes an approach for addressing potential gaps in continuity of critical weather and other Earth
observations begun by SeaWiFS, MODIS and MISR with single band CubeSat imagers that could be used in
combination either onboard a single host satellite or in a constellation of small satellites to provide stable, high SNR
multispectral measurements. These wide field of view, high SNR imagers are enabled by large format (~4000
element long) ultraviolet-near infrared focal plane assemblies and achromatic wide field of view telescopes. This
new class of wide field of view pushbroom imagers offers capability to continue SeaWiFS, MODIS, MISR and, as
discussed in a companion paper, DMSP OLS measurements in support of operational weather observations, Earth
imaging and Earth science studies. In addition, extension of the spectral response to 350 nm enables supplementing
existing and future systems with multispectral observations at near ultraviolet wavelengths of importance to aerosol
and ocean color measurements. The large format size of the array and high optical quality wide field of view
telescope enable an entire ~3000 km wide MODIS or VIIRS swath to be collected simultaneously by a pushbroom
imaging radiometer in polar sun synchronous orbit. The increase in effective integration time made possible by a
pushbroom approach versus the whiskbroom imaging approaches of AVHRR, MODIS and VIIRS enables
measurements with the required SNR using a telescope aperture so small that the entire instrument can fit on a 3U
CubeSat. Small single purpose imager modules like this could be used to supplement much larger systems like
VIIRS by providing measurements of scientifically important bands not in VIIRS like the MODIS chlorophyll
fluorescence and near-infrared water vapor bands and fill possible gaps in measurement continuity not provided by
future systems or resulting from program delays.
