The NSF Firefly CubeSat is a 3U mission designed to perform cutting-edge science, as a secondary payload1,2. Firefly will be the first dedicated mission launched to study Terrestrial Gamma ray Flashes (TGFs), their link to lightning, and their effect in producing energetic electrons that may become stably trapped in the inner radiation belt. Firefly demonstrates the capability of small missions such...
This paper describes an empirical correction for a time-varying radiometric calibration error present in the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI). The Tb error is modeled as a function of the spacecraft orbit position and solar angles based on observed systematic differences between the TMI 10 GHz vertically polarized (10V) channel oceanic Tb's as compared to a radiative...
Continuation of the Earth Radiation Budget (ERB) Climate Data Record (CDR) has been identified as critical in the 2007 NRC Decadal Survey, the Global Climate Observing System WCRP report, and in an assessment titled `Impacts of NPOESS Nunn-McCurdy Certification on Joint NASA-NOAA Climate Goals'. In response, the final existing CERES Flight Model (FM-5) will fly on the NPP spacecraft for launch in...
The Aeronomy of Ice in the Mesosphere (AIM) Mission is the first detailed exploration of Earth's Polar Mesospheric Clouds (PMCs). AIM was selected from NASA's 1999 Small Explorer (SMEX) Announcement of Opportunity to accomplish the first detailed observations of these clouds to aid our understanding of how and why they form. Polar Mesospheric Clouds form during the polar summers. These clouds have...
