GOES-R Introduction

• GOES-R series being developed to provide
  geostationary continuity to the GOES-N series
• First launch planned no earlier than 2014
• Significant improvement in technology over
  GOES-I/M and GOES-N/O/P series
• Improved Radiometrics
• Improved Navigation
• Operates through Eclipses
• Five new instruments (ABI, GLM, SEISS, EXIS and
  SUVI)
• Radically increased performance and data rates

GOES-R Baseline Instruments to Meet User
Requirements

• Advanced Baseline Imager (ABI)
• Monitors and tracks severe weather
• Images clouds to support forecasts
• Better resolution (4X), faster coverage (5X),
  more bands (3.2X) and more coverage
  simultaneously
• Geostationary Lightning Mapper (GLM)
• Detects lightning strikes as an indicator of
  severe storms
• Continuous coverage of total lightning flash rate
  over land and water
• Solar/Space Monitoring (SUVI, EXIS, SEISS)
• Images the sun and measures solar output to
  monitor solar storms (SIS)
• Measures magnetic fields and charged particles
  (SEISS)
• Enables early warnings for satellite and power
  grid operations, telecom services, astronauts,
  and airlines
• Better Imager (UV over X-Ray)
• Better Heavy Ion detection, adds low energy
  electrons and protons

GOES-R Metadata Collection Points

• Level 0 Data
• Reconstructed unprocessed instrument data at full
  resolution any and all communications artifacts
  (e.g., synchronization frames, communications
  headers) removed
• Level 1b Products
• Level 0 data with radiometric and geometric
  correction applied to produce parameters in
  physical units
• GOES-R Rebroadcast (GRB) Data
• Level 1b selected Level 2 Products
• Level 2 Products
• Level 2 and higher GOES-R Products

7
GOES-R Referenced Standards

• ISO 19115 Geographic Information - Metadata
• Mandatory attributes and applicable optional
  attributes
• ISO 19115 Part 2 Extensions for Imagery and
  Gridded Data
• ISO 19121 Imagery and Gridded Data
• ISO 19130 Sensor and Data Model for Imagery and
  Gridded Data
• ISO 19136 Geography Markup Language
• ISO 19138 Data Quality Measures
• ISO 19139 Metadata XML Schema Implementation
• FGDC Conformance

Discussion Issues

• Need to define a suitable data model for GOES-R
  Products
• Will need to map ISO Standard(s) to GOES-R Data
  Model
• Need to identify a standard way of representing
• Provenance/History
• Operational Quality
• Anomaly Recognition
• Quasi-metadata (test results, event logs,
  performance records)
• Need to identify suitable conventions for higher
  level products
• Will need to map convention metadata model to
  GOES-R model
• Need to identify suitable format representation
  for metadata
• Will it be carried as payload in the data file or
  separately ?
