Initial Cross-Calibration of Landsat 8 and Landsat 9 Using the Simultaneous Underfly Event
With the launch of Landsat 9 in September 2021, an optimal opportunity for in-flight cross-calibration occurred when Landsat 9 flew underneath Landsat 8 while being moved into its final orbit.

Extended Cross-Calibration Analysis Using Data from the Landsat 8 and 9 Underfly Event
The Landsat 8 and 9 Underfly Event occurred in November 2021, during which Landsat 9 flew beneath Landsat 8 in the final stages before settling in its final orbiting path. An analysis was performed on the images taken during this event, which resulted in

Radiometric Cross-Calibration of GF-4 PMS Sensor Based on Assimilation of Landsat-8 OLI Images
Earth observation data obtained from remote sensors must undergo radiometric calibration before use in quantitative applications. However, the large view angles of the panchromatic multispectral sensor (PMS) aboard the GF-4 satellite pose challenges for ...

Long-term cross calibration of HJ-1A CCD1 and Terra MODIS reflective solar bands. [PDF]
Since its launch on September 6, 2008, HJ-1A has been in the orbit for 13 years. The CCD1 sensor on the HJ-1A has four reflected solar bands. Since the calibration frequency is limited to the annual site calibration, cross-calibration is an effective ...

Radiometer-to-imager in-flight cross calibration and verification
This work develops a method to complete the in-flight cross calibration and verification between a radiometer and an imager hosted on aircraft. The in-flight cross calibration is data transmission through time matching, space matching, and spectral matching of two polarization instruments on the same platform, and this method can not only complete the ...

Radiometric Cross-calibration of GF-6/WFV Sensor Using MODIS Images with Different BRDF Models
The wide field of view (WFV) imaging system of the GaoFen-6 (GF-6) satellite processes four popular spectral bands (blue, green, red and NIR) and four new spectral bands (costal, yellow and two red edges).
