he 2017-2027 Decadal Survey for Earth Science and Applications from Space identifies six “Science & Applications Topic”, two of which are “Extending & Improving Weather and Air Quality Forecasts” and “Reducing Climate Uncertainty & Informing Societal Response”. NASA Jet Propulsion Laboratory (JPL) has been developing the Panchromatic imaging Fourier Transform Spectrometer (PanFTS) to address different atmospheric measurements related to these two applications. PanFTS is envisioned as a hosted payload on a geostationary (GEO) communication satellite. This offers the access to GEO with “a fee”, vs the costs associated with a dedicated launch vehicle and spacecraft. In parallel, the NOAA Satellite Observing System Architecture Study (NSOSA) report calls for “… a small number of GEO hosted instruments.”


Similar to CrIS, PanFTS is a Fourier transform spectrometer (FTS). CrIS is a point mapping spectrometer. It has three different spectral bands of 3 x 3 photo detectors, mapping 9 ground pixels simultaneously. PanFTS is an imaging spectrometer. It has 1 - 3 imaging cameras, mapping 0.3 - 1 million ground pixels simultaneously. The several orders of improved observation throughput is enabled by the high speed cameras and the matching high speed onboard data processing electronics. PanFTS successfully completed a NASA Earth Science Technology Office Instrument Incubator Program (ESTO IIP) task in 2011. An engineering model (EM) was built. PanFTS - EM spanned 0.29 - 16 um wavelength, and it could achieve a spectral resolution DeltaR = 0.05 cm-1. PanFTS - EM performances were characterized in a thermal vacuum chamber at 110K, and the results were independently reviewed. However, PanFTS - EM occupied a ~1.5 m3 volume. We propose to miniaturize PanFTS (uPanFTS) into a ~6 - 12 U volume using a 2-color camera technology. This camera technology has been developed by the DOD sponsors over the last two decades, and it is currently deployed in the fields.
