MODIS reflective solar bands uncertainty analysis
SPIE Proceedings, 2004A key instrument for the NASA Earth Observing System (EOS) mission, the Moderate Resolution Imaging Spectroradiometer (MODIS), is currently operating on-board the Terra and Aqua spacecrafts. This paper discusses the calibration uncertainty analysis for the MODIS Reflective Solar Bands. Each MODIS, either on the Terra or on the Aqua spacecraft, has 20

On-orbit noise characterization of the SNPP VIIRS reflective solar bands
Earth Observing Systems XXII, 2017The Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the Suomi National Polar-orbiting Partnership satellite has 14 reflective solar bands (RSBs) covering a spectral range from 410 nm to 2250 nm. We provide an overview of the noise characterization of the VIIRS RSB from pre-launch through more than five years of on-orbit operation.

An Overview of Terra MODIS Reflective Solar Bands On-orbit Calibration
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006The first MODIS instrument was launched aboard NASA's EOS Terra spacecraft in December 1999. MODIS has 20 reflective solar bands (RSB) with wavelengths from 0.41 to 2.2 mum and nadir spatial resolutions of 0.25 km, 0.5 km, and 1.0 km. It also has 16 thermal emissive bands (TEB) with wavelengths from 3.7 to 14.4 mum, all with 1.0 km spatial resolution ...

Mission history of reflective solar band calibration performance of VIIRS
SPIE Proceedings, 2015Environmental Data Records (EDR) from the Visible Infrared Imaging Radiometer Suite (VIIRS) have a need for Reflective Solar Band (RSB) calibration errors of less than 0.1%. Throughout the mission history of VIIRS, the overall instrument calibrated response scale factor (F factor) has been calculated with a manual process that uses data at least one ...

VIIRS reflective solar bands on-orbit calibration using the moon
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015The Visible Infrared Imager Radiometer Suite (VIIRS) has been on-orbit for more than three and half years. It has been scheduled to view the moon approximately monthly since its nadir door open on November 21, 2011. The scheduled lunar observations have been used to monitor the VIIRS reflective solar bands (RSB) on-orbit gain changes. The VIIRS RSB are

On-Orbit Calibration and Performance of NOAA-20 VIIRS Reflective Solar Bands
IEEE Transactions on Geoscience and Remote Sensing, 2022The NOAA-20 (N20) satellite was launched on November 18, 2017 carrying the second Visible Infrared Imaging Radiometer Suite (VIIRS) instrument. Immediately following the launch, the VIIRS passed a series of intensive calibration and validation tests, after which regular calibration and operation activities have continued successfully for more than ...

SUOMI NPP VIIRS reflective solar band radiometric calibration
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012The Visible-Infrared Imaging Radiometer Suite (VIIRS) is a primary sensor onboard the National Polar-orbiting Partnership (NPP) satellite launched on October 28, 2011. It collects data over the spectral range of 0.4–12.5 um and consists of 15 reflective solar bands (RSB) and 7 thermal emissive bands (TEB).

Analog and digital saturation in the MODIS reflective solar bands
SPIE Proceedings, 2012The MODIS instrument on the Terra and Aqua spacecrafts is a 12 bit sensor with an analog-to-digital (A/D) range of 0 to 4095 DN. Each sensor system is limited by a range at the low and high ends of the dynamic scale. At the low end, quantization noise is the limiting factor whereas at the high end the maximum value is limited by the capability of the ...

MODIS reflective solar bands unscheduled lunar observations
SPIE Proceedings, 2007The MODIS Protoflight Model (PFM) on-board the Terra spacecraft and the MODIS Flight Model 1 (FM1) on-board the Aqua spacecraft were launched on December 18, 1999 and May 4, 2002, respectively. They are scheduled to view the Moon at a fixed Sun-Moon-MODIS phase angle (-55° for Aqua and 55° for Terra) through the space view (SV) port approximately ...

MODIS reflective solar bands calibration improvements for Collection 7
Sensors, Systems, and Next-Generation Satellites XXV, 2021Calibration of Terra and Aqua MODIS reflective solar bands (RSB) has evolved significantly since the launch of the first MODIS instrument on the Terra satellite more than 21 years ago. In NASA’s current Collection 6 and 6.1 Level 1B products (C6/C6.1 L1B), the RSB calibration algorithm continues to rely primarily on the onboard solar diffuser to ...
