Landsat 9 Micrometeoroid and Orbital Debris Mission Success Approach
First Int'l. Orbital Debris Conf. 2019 (LPI Contrib. No. 2109) 6058.pdf Landsat 9 Micrometeoroid and Orbital Debris Mission Success Approach Michael S. Pryzby(1), Scott M. Hull(2), Angela M. Russo(2), Glenn T. Iona(2), Daniel Helfrich(2), and Evan H. Webb(2) (1) ATA Aerospace, 7474 Greenway Center Dr, Suite 500, Greenbelt, MD 20770, USA (2) NASA Goddard Space Flight Center, 8800 Greenbelt Rd, Greenbelt, MD 20771, USA ABSTRACT Landsat 9* (L9) is the successor mission to Landsat 8 (L8) previously known as Landsat Data Continuity Mission (LDCM). Both missions are large unmanned remote sensing satellites operating in sun- synchronous polar orbits. As opposed to L8/LDCM, systems engineers for L9 incorporated Micrometeoroid/Orbital Debris (MMOD) protection for small object collisions as part of the L9’s mission success criteria. In other words, the NASA Process for Limiting Orbital Debris (NASA-STD-8719.14A) only calls for analyses of the protection of disposal-critical hardware, but L9 opted to also assess and provide small particle penetration protections for all observatory components including instruments that are not part of the spacecraft components needed for controlled reentry. Systems engineers at Goddard developed a design process to protect against MMOD during the life of Low Earth Orbit (LEO) observatories, and in particular the Landsat 9 Mission. Simply stated, this design process enhanced the effectiveness of existing Multi-Layer Insulation (MLI) to provide the needed protection. The end goal of the design process was to establish a necessary blanket areal density for a given electronics box or instrument wall thickness and a separation between the outer MLI blanket and the structure underneath. -
Spatiotemporal Continuous Impervious Surface Mapping by Fusion of Landsat Time Series Data and Google Earth Imagery

Spatiotemporal super-resolution mapping (STSRM) fuses fine-spatial-coarse- temporal remote sensing data with coarse-spatial-fine-temporal data, allowing for urban impervious surface mapping at both fine-spatial and fine-temporal resolutions. The STSRM involves two main steps: unmixing the coarse-spatial-fine-temporal remote sensing data to class fraction images, and Citation: Chen, R.; Li, X.; Zhang, Y.; downscaling the fraction images to sub-pixel land cover maps. -
CLARREO Pathfinder/VIIRS Intercalibration
remote sensing Article CLARREO Pathfinder/VIIRS Intercalibration: Quantifying the Polarization Effects on Reflectance and the Intercalibration Uncertainty Daniel Goldin1,2,*, Xiaoxiong Xiong 3, Yolanda Shea 2 and Constantine Lukashin 2 1 Science Systems and Applications, Inc., (SSAI), Hampton, VA 23666, USA 2 NASA Langley Research Center, Hampton, VA 23666, USA 3 NASA Goddard Space Flight Center, Greenbelt, MD 20771, USA * Correspondence: [email protected] Received: 2 July 2019; Accepted: 12 August 2019; Published: 16 August 2019 Abstract: Atmospheric scattering and surface polarization affect radiance measurements of polarization-sensitive instruments on orbit. Neglecting the polarization effects may lead to an inaccurate radiance/reflectance determination and underestimated radiance/reflectance uncertainty. Of the two instruments, CERES and VIIRS, slated to be intercalibrated by the CLARREO Pathfinder (CPF), the latter is known to be sensitive to polarization. The Pathfinder mission is tasked with accurately determining the uncertainty contribution of polarization and will provide the benchmark for the determination of the polarization correction factor for polarization-sensitive instruments. In this article, we show the formalism necessary to correct the reflectance for sensitivity to polarization after the CLARREO Pathfinder/VIIRS intercalibration, as well as the associated polarization uncertainty contribution to the overall intercalibrated reflectance error. To illustrate its usage, the formalism is applied to three dominant scene types. Keywords: VIIRS; CLARREO Pathfinder; CPF; intercalibration; polarization; reflectance; reflectance correction; polarization uncertainty 1. Introduction CLARREO Pathfinder and VIIRS Missions In 2007, the National Research Council’s Earth Science Decadal Survey recommended the implementation of Climate Absolute Radiance and Refractivity Observatory (CLARREO) [1] as a Tier-1 mission. -

Early Analysis of Landsat-8 Thermal Infrared Sensor Imagery of Volcanic Activity

Just weeks after it entered active service, its sensors observed activity at Paluweh Volcano, Indonesia. Given that the image acquired was in the daytime, its shortwave infrared observations were contaminated with reflected solar radiation; however, those of the satellite’s Thermal Infrared Sensor (TIRS) show thermal emission from the volcano’s summit and flanks. These emissions detected in sensor’s band 10 (10.60–11.19 µm) have here been quantified in terms of radiant power, to confirm reports of the actual volcanic processes operating at the time of image acquisition, and to form an initial assessment of the TIRS in its volcanic observation capabilities. Data from band 11 have been neglected as its data have been shown to be unreliable at the time of writing. At the instant of image acquisition, the thermal emission of the volcano was found to be 345 MW. This value is shown to be on the same order of magnitude as similarly timed NASA Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer thermal observations. -

And it was indeed a fortunate coincidence that the ninth session of the WMO Executive Committee – known today as the WMO Executive Council (EC) – was in progress precisely at this moment, for the EC members were very quick to realize that satellite technology held the promise to expand the volume of meteorological data and to fill the notable gaps where land-based observations were not readily available. -
