JAXA's Data Policy for Earth Observation Satellites JAXA's Data Policy for Earth Observation Satellites January 13, 2014 Chu Ishida Senior Chief Officer of International Affairs Space Applications Mission Directorate I Japan Aerospace Exploration Agency (JAXA) 1. JAXA’s activity for GEO/DSWG JAXA changed the data distribution policy for earth observation satellites in August, 2013 ← GEOSS Data Sharing Principles JAXA contributes to - GEOSS Common Infrastructure - GEOSS Data-Core 1 2. Data distribution policy for Earth Observation Satellites 2. Data distribution policy for Earth Observation Satellites (revised in August, 2013) Defined two categories as follow; A. Data with Low or Middle resolution B. Data with High resolution 2 2. Data distribution policy for Earth Observation Satellites A. Data with Low or Middle resolution i) In principle, the data with Low or Middle resolution such as earth environment monitoring satellite data is distributed with “ full and open access” policy. ii) JAXA accepts non-discriminatory use and re- distribution of those satellite data by users. 3 2. Data distribution policy for Earth Observation Satellites A. Data with Low or Middle resolution Following conditions remain unchanged The data itself is free-of-charge (*: such as cost for media) Distribution cost* could be charged by JAXA Registration is required for only direct distribution Source of the data should be indicated In general, the policy is applied to the distribution of standard data products. Data policies for other data products such as Level 0 data (raw data) and value added data products are determined respectively. 4 2. Data distribution policy for Earth Observation Satellites B. Data with High resolution i) Limited amount of data is provided to the user for the purpose of Disaster Management, Scientific Research, free of charge ii) Distribution with the marginal cost to government users under the cooperative agreement iii) Private business operator distribute data with commercial price 5 3. Advanced Land Observing Satellite-2 （ALOS-2) ALOS-2 Data will be distributed under “full and open access” policy. JAXA will directly distribute the limited amount of data to agencies or organizations at the marginal cost or free-of- charge under cooperative agreement framework for the government’s disaster measures, other government inter- national cooperations and calibration & validation purposes. JAXA will distribute limited amount of the data for Research Announcement (RA) users for scientific research use. JAXA will distribute the data through a private business operator for general use.

    IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING, VOL. 41, NO. 2, FEBRUARY 2003 173 Aqua: An Earth-Observing Satellite Mission to Examine Water and Other Climate Variables Claire L. Parkinson Abstract—Aqua is a major satellite mission of the Earth Observing System (EOS), an international program centered at the U.S. National Aeronautics and Space Administration (NASA). The Aqua satellite carries six distinct earth-observing instruments to measure numerous aspects of earth’s atmosphere, land, oceans, biosphere, and cryosphere, with a concentration on water in the earth system. Launched on May 4, 2002, the satellite is in a sun-synchronous orbit at an altitude of 705 km, with a track that takes it north across the equator at 1:30 P.M. and south across the equator at 1:30 A.M. All of its earth-observing instruments are operating, and all have the ability to obtain global measurements within two days. The Aqua data will be archived and available to the research community through four Distributed Active Archive Centers (DAACs). Index Terms—Aqua, Earth Observing System (EOS), remote sensing, satellites, water cycle. I.

  • NASA's Aqua and GPM Satellites Examine Tropical Cyclone Kenanga 17 December 2018
    NASA's Aqua and GPM satellites examine Tropical Cyclone Kenanga 17 December 2018 northeast of Kenanga's center of circulation was dropping rain at a rate of over 119 mm (4.7 inches) per hour. At NASA's Goddard Space Flight Center in Greenbelt, Maryland, imagery and animations were created using GPM data. A 3-D animation used GPM's radar to show the structure of precipitation within tropical Cyclone Kenanga. The simulated flyby around Kenanga showed storm tops that were reaching heights above 13.5 km (8.4 miles). GPM is a joint mission between NASA and the Japanese space agency JAXA. On Dec. 17 at 3:05 a.m. EST (0805 UTC), NASA's Aqua satellite provided an infrared look at Tropical Cyclone Kenanga. Coldest cloud top temperatures (in purple) indicated where strongest storms appeared. Credit: NASA JPL/Heidar Thrastarson On December 16 and 17, NASA's GPM core observatory satellite and NASA's Aqua satellite, respectively, passed over the Southern Indian Ocean and captured rainfall and temperature data on Tropical Cyclone Kenanga. Kenanga formed on Dec. 15 about 1,116 miles east of Diego Garcia, and strengthened into a tropical storm.

  • Intercalibration of Broadband Geostationary Imagers Using AIRS
    746 JOURNAL OF ATMOSPHERIC AND OCEANIC TECHNOLOGY VOLUME 26 Intercalibration of Broadband Geostationary Imagers Using AIRS MATHEW M. GUNSHOR Cooperative Institute for Meteorological Satellite Studies, University of Wisconsin—Madison, Madison, Wisconsin TIMOTHY J. SCHMIT NOAA/NESDIS, Center for Satellite Applications and Research, Advanced Satellite Products Branch, Madison, Wisconsin W. PAUL MENZEL AND DAVID C. TOBIN Cooperative Institute for Meteorological Satellite Studies, University of Wisconsin—Madison, Madison, Wisconsin (Manuscript received 14 April 2008, in final form 19 August 2008) ABSTRACT Geostationary simultaneous nadir observations (GSNOs) are collected for Earth Observing System (EOS) Atmospheric Infrared Sounder (AIRS) on board Aqua and a global array of geostationary imagers. The imagers compared in this study are on (Geostationary Operational Environmental Satellites) GOES-10, GOES-11, GOES-12, (Meteorological Satellites) Meteosat-8, Meteosat-9, Multifunctional Transport Satellite-IR (MTSAT-IR), and Fenguyun-2C (FY-2C). It has been shown that a single polar-orbiting satellite can be used to intercalibrate any number of geostationary imagers. Using a high-spectral-resolution infrared sensor, in this case AIRS, brings this method closer to an absolute reckoning of imager calibration accuracy based on laboratory measurements of the instrument’s spectral response. An intercalibration method is presented here, including a method of compensating for AIRS’ spectral gaps, along with results for approximately 22 months of comparisons. The method appears to work very well for most bands, but there are still unre- solved issues with bands that are not spectrally covered well by AIRS (such as the water vapor bands and the 8.7-mm band on Meteosat). To the first approximation, most of the bands on the world’s geostationary imagers are reasonably well calibrated—that is, they compare to within 1 K of a standard reference (AIRS).

    NON-PEER REVIEW Please select category below: Normal Paper Student Paper Young Engineer Paper BepiColombo: Flight Dynamics Operations during Launch and Early Orbit Phase F. Budnik 1, G. Bellei 2, F. Castellini 3 and T. Morley 3 1 ESOC/ESA, Robert-Bosch-Str. 5, 64393 Darmstadt, Germany 2 DEIMOS Space located at ESOC 3 Telespazio VEGA Deutschland GmbH located at ESOC Abstract BepiColombo was launched on 20 October 2018 to begin its 7 years of interplanetary cruise towards Mercury. The purpose of the paper is to report on the Flight Dynamics activities that have been conducted at ESA’s European Space Operations Centre (ESOC) during the Launch and Early Orbit Phase (LEOP). The first three introductory sections give an overview of the BepiColombo mission, the spacecraft design and the baseline cruise trajectory, as far as is relevant for the paper. The remainder of the paper focuses on the LEOP activities. Firstly, the launch, signal acquisition at the ground stations, and the initial spacecraft operations are described. Subsequently, the focus is put onto orbit determination activities, its configuration, the available tracking data and their quality assessment as well as the launcher separation state assessment. Finally, the results of three chemical propulsion test manoeuvres are presented. The paper closes with the current status and outlook of near-term, future operational activities for BepiColombo. Keywords: BepiColombo, LEOP, Flight Dynamics Operations, Orbit Determination, Mercury The BepiColombo Mission BepiColombo is a European Space Agency (ESA) cornerstone mission to Mercury which is being conducted in co-operation with Japan. The Mercury Planetary Orbiter (MPO) is ESA's scientific contribution to the mission.

  • EBAF Update Norman G
    EBAF Update Norman G. Loeb and Dave Doelling NASA Langley Research Center, Hampton, VA CERES Science Team Meeting, April 28-30, 2020 Virtual Meeting Background • CERES EBAF leverages other CERES data products to provide a spatially and temporally complete representation of ERB. Advances include: - One-time adjustment within uncertainty to SW and LW fluxes such that 10-year mean (2005-2015) EEI is consistent with EEI determined from in-situ data (mainly Argo). - SW diurnal correction methodology that overcomes GEO artifacts. - Clear-sky “filling” with imager to avoid gaps in clear-sky maps. - Determination of clear-sky for total region, consistent with GCM definition. - Objective “tuning” of input variables used in Langley Fu-Liou to determine surface fluxes constrained by EBAF TOA fluxes. • Currently uses only Terra and Aqua data, whose equator crossing mean local times (MLTs) have been maintained as close as possible to 1030 for Terra and 1330 for Aqua. • However, Terra’s MLT will start to drift in January 2021 and Aqua’s MLT will start to drift in March 2022. Mean Local Time of Equator Crossing for Terra’s Descending and Aqua’s Ascending Nodes EBAF SW Empirical Diurnal Correction: Methodology • Objective: Maintain the excellent calibration stability of CERES SSF1deg while at the same time preserving the diurnal information in SYN1deg without GEO artifacts. • Approach: Apply pre-determined empirical diurnal corrections to daily mean regional SSF1deg SW fluxes over the GEO area of coverage (60S-60N) and average over each month. • Diurnal corrections: Consist of diurnal correction ratios (DCRs), where DCR = SYN1deg-to-SSF1deg flux ratios, derived from daily mean SW TOA fluxes between July 2002 and June 2015.
