Technical algorithm specification describing the processing of OLI lunar imagery to compute integrated lunar irradiance and associated geometric parameters for calibration and comparison with the RoLO lunar irradiance model.
Program: OLI Lunar Irradiance Characterization
Instrument: Operational Land Imager (OLI)
Related System: Robotics Lunar Observatory (RoLO), USGS/Flagstaff
Maturity Level: Level 2 (reuse from ALIAS)
Acquisition Frequency: Approximately once per month at ~7 degrees lunar phase angle
Primary Input Product: L1R lunar product
Primary Output: Integrated lunar irradiances and geometric parameters
Data Exchange Interface: IAS–RoLO data interchange files
Measured Quantities: Integrated irradiance, apparent lunar Y-size, spacecraft position vector
Modeled Quantities: Modeled and scaled irradiances, lunar geometry parameters
Units: µW/m²/nm, mrad, km, degrees
Coordinate Reference: J2000 GCI
Processing Elements: Lunar mask generation, median filtering, radiance thresholding, geometric parameter extraction
Database Interaction: Ingestion and trending of measured and modeled irradiance comparisons
Known Limitations: Missing SCA illumination flag in ancillary database; lunar and Earth distance parameters not directly available
Operational Entities: IAS, RoLO, mission operations element
Price: 8 / 10 USD
