Summary

Reflectance data were collected using Malvern Panalytical ASD FieldSpec® 4 Hi-Res NG Spectroradiometers with custom VNIR gratings (hereafter referred to as ASD spectrometers) on August 21, 2022, at a field site on Black Rock Desert, Nevada, USA. A full description of all collection and processing steps is included in this data release as ‘BlackRockDesertNV_21aug2022_ProcessingSteps.pdf’. These data are useful for comparison with imaging spectrometer data collected from aircraft, e.g., AVIRIS-Classic (Vane and others, 1993), and from space, e.g., EMIT (Thompson and others, 2023; Green and others, 2021) and EnMAP (Storch and others, 2023). Because the field data have fine spectral resolution and were collected over a large area, they [...]

Purpose

ASD spectrometer data were collected in the field for comparison with imaging spectrometer data collected from aircraft, e.g., AVIRIS-Classic (Vane and others, 1993), and from space, e.g., EMIT (Thompson and others, 2023, Green and others, 2021) and EnMAP (Storch and others, 2023). Because the field data have fine spectral resolution and were collected over a large area, they are applicable to calibration or validation of these and other airborne and spaceborne imaging spectrometers and multispectral sensors.
