• Section 8 describes the calibration integrity task. The primary objective of this task isthe validation of the Level 1B1 Radiometric Product. Sensor cross-comparisons aremade, and lunar observation data are tracked (if available) as part of the radiometriccalibration verification program. Additionally, this section covers quality assessmentand traceability of the radiance scale.• Section 9 is the management description, including personnel and computingresources, and the top-level schedule.• Section 10 provides open-literature references from peer-reviewed and conferencepublications.The appendices provide:• IFRCC nomenclature; and• details of the on-orbit calibration mode sequences.1.3 APPLICABLE DOCUMENTSThroughout this document a notation of the form [shorthand] will be used to referenceproject documents. The actual references and associated [shorthand] definitions are listed inSections 1.3.1 and 1.3.2. Open literature references are pointed to by means of superscriptnumbers in the text. These numbers refer to the publications listed in Chapter 10.Other MISR calibration activities are described elsewhere. Specifically, the preflightcalibration plan is described in [PreCal Plan]; and in-flight geometric calibration is described in[GeoCal Plan]. The latter activity is required for generation of the Level 1B2 GeorectifiedRadiance Product. The provision of top-of-atmosphere vicarious radiances across the spectrum atMISR view angles, is provided by the Validation Team, and is discussed in [Val Plan]. (Theseradiances are used by the IFRCC team to establish a vicarious instrument calibration.) Controllingdocuments for the IFRCC program include the [ISR] and the [FDR], which define the instrumentrequirements. Included in the reference section are summary publications of the MISR calibrationprogram 1, 3 .Following publication of this plan, the IFRCC team will prepare two algorithm theoreticalbasis documents. The first, [L1Rad ATB], is a revision to the current [L1B1 ATB], whichdescribes the algorithms used to produce the Level 1B1 Radiometric Product. Processing for thisproduct will occur at the Distributed Active Archive Center (DAAC). The second document is the[IFRCC ATB]. This describes the algorithms which will routinely run at the JPL ScienceComputing Facility (SCF). In simplified terms, the [IFRCC ATB] describes the instrumentcalibration process, the [L1Rad ATB] describes the radiance retrieval process.1.3.1 Controlling project documents[shorthand]Reference1.
