Abstract
European Meteorological Operational satellite program (Metop)-C was successfully launched into low Earth orbit at 00:47 UTC on November 7, 2018. METOP-C is the third and final spacecraft of the Metop. The Metop-C satellite carries a variety of instruments including three NOAA sensors: Advanced Microwave Sounding Unit-A (AMSU-A), Advanced Very High Resolution Radiometer (AVHRR), and the Space Environment Monitor (SEM). Both of AMSU-A and AVHRR will improve daily weather forecasts while continuing to monitor long-term changes in Earth’s climate. SEM provides measurements to determine the intensity of the Earth’s radiation belts and the flux of charged particles at satellite altitude.
On November 12, 2018, the AVHRR onboard the METOP-C became the first instrument to acquire and disseminate its visible (0.64 µm) and near infrared (0.86 µm and 1.61 µm) data. Nine days after METOP-C was launched, the first day AMSU-A science data was received on November 15, 2018. The Center for Satellite Applications and Research (STAR) in NOAA A is leading a series of calibration and validations (CalVal) activities about AMSU-A and AVHRR Sensor Data Record (SDR) data. The Metop-C AMSU-A and AVHRR SDR CalVals have successfully reached to their beta maturity review on 15 February 2019. A briefing will be presented about status and prospective of Metop-C AMSU-A and AVHRR CalVal. In particular, we will introduce AMSU-A instrument noise performance, Lunar intrusion correction, antenna pattern correction, SDR data quality assessment for AMSU-A by using the JCSDA Community Radiative Model (CRTM), intersensor comparison and double difference methods. We will brief IR Noise Equivalent delta-Temperature (NEdT), Solar channels calibration and other CalVal results for AVHRR instrument and SDR data. Additionally, we will brief the STAR Integrated Calibration and Validation (ICVS) to provide near-real time monitoring for both AMSU-A and AVHRR instrument performance and SDR data quality.
