Outline Introduction Status WMO OSCAR Status preparing Landing Pages for WMO OSCAR Use of common Nomenclature and Standards

Introduction

CGMS and GSICS Actions CGMS-43: WGII/3 Action 43.01 Calibration events logging task team to prepare a white paper outlining the set of parameters, the nomenclature, and the standards to be used for reporting on instrument calibration across space agencies. GSICS GRWG/GDWG 2014 Action 33: All GPRCs to provide satellite instrument specific links to calibration events to WMO-OSCAR.

Status Update WMO OSCAR http://www.wmo-sat.info/oscar/

WMO OSCAR WMO OSCAR has been updated in 2015; WMO OSCAR now offers one link per Satellite per Instrument that points to a landing page with information on instrument calibration events; Most Satellite Operators provided addresses of stable landing pages that guide the visitors to instrument calibration databases; JMA and EUMETSAT prepared (or are preparing) stable landing pages that guide the visitors to four information categories (as proposed to CGMS and GSICS), i.e.: Instrument Specifications Instrument Events Data Outages Instrument Monitoring GSICS recommends the Satellite Operators to prepare landing pages per Satellite per Instrument that include the proposed four information categories; WMO recommends the Satellite Operators to list the most relevant Instrument Specifications of future missions about 3 to 4 years prior to launch (email Jerome Lafeuille);

Update WMO OSCAR web portal (http://www.wmo-sat.info/oscar/) Example WMO OSCAR Page -> Satellite: Himawari-7 (MTSAT-2)

Landing Pages – Categories suggested to CGMS and GSICS Landing Page Categories Instrument Specifications Instrument Events Instrument Monitoring Data Outages Instrument Specifications General information on the platform, instruments, and sensors operated in the mission that is relevant to all users of the satellite data (see OSCAR website). Instrument Events Database (and graphical interface) of events at satellite and processing level that are not occurring systematically and that impact the radiometric or geometric quality of the observations due to instruments calibrations, manoeuvres or miscellaneous. Instrument Monitoring Database (and graphical interface) of quasi continues information on the present state of the instruments and sensors operated on the platform; Data Outages Events that triggered the temporary or definitive end of the data collection.

Examples - Landing Pages Example - GOME Landing page (EUMETSAT) Example - Himawari Landing page (JMA)

Landing Page – Instrument Specifications Note: WMO (Jerome Lafeuille) requests Satellite Operators to provide the Instrument Specifications of further instruments (typically 2-3 years before launch). The concept of Landing Pages is suited to address this request if: Satellite Operators would prepare landing pages for future instruments Satellite Operators would provide the landing page links to WMO

Common Nomenclature and Standards

Common Nomenclature and Standards CGMS-43: WGII/3 Action 43.01 Calibration events logging task team to prepare a white paper outlining the set of parameters, the nomenclature, and the standards to be used for reporting on instrument calibration across space agencies. A paper is being drafted and will be distributed to the Task Team soon

Common Nomenclature and Standards  [RSP/TJH1]How would define these as single events? Start/end time + rate of drift? Common Nomenclature and Standards It is proposed to group Instrument Events in three Categories For each Category a list of most frequent Instrument is drafted Radiometric Calibration Events general announcement spacecraft maintenance spacecraft anomaly radiometric calibration drift  radiometric calibration anomaly radiometric calibration correction Instrument Event Categories IRREGULAR EVENTS Radiometric Calibration Events Geometric Calibration Events PROCESSING EVENTS Processing Updates Reprocessing Events DATA OUTAGES Instrument Outages Ground Segment Outages Data Outages general announcement spacecraft maintenance spacecraft anomaly instrument maintenance instrument anomaly ground-segment maintenance ground-segment anomaly in-plane-manoeuvre out-of-plane-manoeuvre eclipse-season lunar-eclipse

Common Nomenclature and Standards  [RSP/TJH1]How to deal with instantaneous events? Start=End, or just Start?  [RSP/TJH1]How would define these as single events? Start/end time + rate of drift? Common Nomenclature and Standards It is proposed to provide for each event a limited set of mandatory attributes Attributes name Attributes value Mission type LEO or GEO Satellite [satellite name] Satellite details-> Link to satellite details Instrument [instrument name] Instrument details-> Link to instrument details Prelaunch characteristics -> Link to mission specifications document Impact [impact class] Start date [<yyyy-mm-dd>T<hh:mm>Z] End date [<yyyy-mm-dd>T<hh:mm>Z]  Product type Product description Category [from list of categories] Event type [from lists of standard event type names] Event description [short description of the event] Event report -> Link to the full event report

Proposed Actions to GRWG/GDWG

Proposed Actions to GSICS All Satellite Operators to provide satellite instrument specific links to calibration events to WMO-OSCAR. All Satellite Operators to prepare landing pages per Satellite per Instrument that include the proposed four information categories; All Satellite Operators to list the most relevant Instrument Specifications of future missions about 2 to 3 years prior to launch (email Jerome Lafeuille (new point of contact Stephan Bojinski); All Satellite Operators to seek common naming conventions and common attribute standards for instrument events at Main-Category and Event Names level.
