Our team at NASA Goddard Space Flight Center is advancing the maturation of a hyperspectral microwave sensor in response to the 2017 Earth Science Decadal Survey, which recommended that NASA create a new Incubation Program to explore and develop new technologies to probe the Earth’s planetary boundary layer (PBL) by 2027.
The hyperspectral evaluation of the microwave spectra will enable more precise characterization of the state of the atmosphere in this key region. Our instrument, the hyperspectral microwave photonic instrument (HyMPI), is based on photonic integrated technology to enable the parallel processing of the wideband microwave signals and to minimize the instrument size, mass, and power consumption. The single HyMPI module has been developed to provide wideband (~40-GHz), high-resolution (~10-MHz) measurements of the thermal microwave spectrum. This will improve information content in key variables determining the Earth’s radiation budget such as the water vapor continuum, surface emissivity, hydrometeor microphysics and the PBL thermodynamics. These improved measurements will have broad implications for numerical weather prediction and climate science.
In the last year, we improved the design and performance of the photonic integrated circuits and system. In this work, we will present the progress related to the instrument architecture together with the system performance.
