“…It has been in use for over 25 years, and is a mature, well-understood procedure [9][10][11][12]. Measurements of the surface and atmosphere are made during a given overpass, and the results are used in a radiative transfer code to determine the TOA quantity for the sensor under test.…”

“…Alkali Lake, Nevada, is used as a supplementary test site when access to one of the other two is restricted. Railroad Valley has been used by RSG since 1996 for such sensors as Landsat 5 Thematic Mapper (TM), Landsat 7 ETM+, the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard Terra and Aqua, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), the Multiangle Imaging SpectroRadiometer (MISR), and the constellation of RapidEye satellites [11,[13][14][15]. It is 15 × 15 km in size, and it is at an altitude of 1435 m. In situ data collected over the past 15 years have revealed that even through the surface reflectance changes throughout the year, it can generally be described as having an annual cyclical pattern.…”

The Ground-Based Absolute Radiometric Calibration of Landsat 8 OLI

This paper presents the vicarious calibration results of Landsat 8 OLI that were obtained using the reflectance-based approach at test sites in Nevada, California, Arizona, and South Dakota, USA. Additional data were obtained using the Radiometric Calibration Test Site, which is a suite of instruments located at Railroad Valley, Nevada, USA. The results for the top-of-atmosphere spectral radiance show an average difference of −2.7, −0.8, 1.5, 2.0, 0.0, 3.6, 5.8, and 0.7% in OLI bands 1-8 as compared to an average of all of the ground-based measurements. The top-of-atmosphere spectral reflectance shows an average difference of 1.6, 1.3, 2.0, 1.9, 0.9, 2.1, 3.1, and 2.1% from the ground-based measurements. Except for OLI band 7, the spectral radiance results are generally within ±5% of the design specifications, and the reflectance results are generally within ±3% of the design specifications. The results from the data collected during the tandem Landsat 7 and 8 flight in March 2013 indicate that ETM+ and OLI agree to each other to within ±2% in similar bands in top-of-atmosphere spectral radiance, and to within ±4% in top-of-atmosphere spectral reflectance.

“…A detailed description of the reflectance-based approach has been presented in previous papers. [29][30][31][32] The two main test sites used by RSG for this work are: Measurements of the atmosphere are made prior to, during, and after the overpass of the platform and sensor under test using an automated solar radiometer. From this, the atmospheric properties are determined, and used as input into a Figure 1.…”

The Terra spacecraft contains five Earth-observation instruments, three of which are multispectral imaging sensors that complement each other in spectral and spatial coverage. The Moderate Resolution Imaging Spectroradiometer (MODIS) has 36 channels ranging from 0.4-14.4 µm, with spatial resolutions of 250, 500, and 1000 m. The Multi-angle Imaging SpectroRadiometer (MISR) uses individual imaging sensors to view the earth at nine discreet angles. Each radiometer has four channels in the visible and near infrared (VNIR), and the nadir-viewing camera has a spatial resolution of 275 m. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) was designed with fourteen bands ranging from 0.5-11.6 µm. It is the high-resolution sensor on Terra, with a spatial resolution of 15 m in the VNIR, and 30 m in the shortwave infrared (SWIR). This work describes the vicarious techniques used to perform the absolute radiometric calibration of MODIS, MISR, and ASTER in the solar-reflective region (0.4-2.5 µm). It includes the reflectance-based approach, which uses ground-based personnel to make in situ measurements during the time of overpass. It also includes more recent results that were obtained using the University of Arizona's automated Radiometric Calibration Test Site (RadCaTS) at Railroad Valley, Nevada. In addition to the absolute radiometric calibration of Terra sensors, RadCaTS is used to perform the cross comparison of MODIS, MISR, and ASTER with Landsat 7 ETM+ and Landsat 8 OLI.

“…The Remote Sensing Group (RSG) of the College of Optical Sciences at the University of Arizona has been directly involved in the pre-flight and post-launch absolute radiometric calibration of a wide array of Earth-observing sensors [7][8][9][10]. Recent efforts have been focused on such sensors as the Landsat 5 Thematic Mapper (TM) [11], Landsat 7 Enhanced Thematic Mapper Plus (ETM+) [12], the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [13], MODIS [14], and MISR [13,15]. The main focus of RSG's research over the past two decades has been the ground-based vicarious calibration of satellite and airborne sensors.…”

This work describes the calibration and characterization of a commercial digital camera that is being evaluated as a potential inexpensive imaging system to measure the bidirectional reflectance factor of the test site surfaces that are used by the Remote Sensing Group for the ground-based vicarious calibration of airborne and spaceborne systems. The main advantage to using a lightweight digital camera in combination with a fisheye lens is that a test site can be simultaneously spatially and spectrally sampled with greater ease. The motivation for using an inexpensive, lightweight digital camera to measure surface bidirectional distribution factor is the ability to spatially sample many points on the ground. An additional benefit to such cameras is their ability to operate without the need for cooling, which was required on a previous camera system developed at the Remote Sensing Group. Laboratory measurements include the gain and offset, spectral responsivity, linearity, cosine response, and point spread function. The results show that the uniformity of the Nikon detector array ranges from 0.7%-1.2%. The spectral bandwidth is approximately 90 nm for the blue channel, and 110 nm for the green, and 75 nm for the red channel. Linearity measurements show that the camera responsivity is nonlinear due to the internal imageprocessing algorithms, and a logarithmic fitting function is suggested. Measurements of the camera response versus the angle of incidence reveal that the camera does not exhibit a cos 4 falloff on detector irradiance as one would expect, which is another consequence of the internal algorithms.
