High angular and spectral directional reflectance dataset of snow and sea-ice

Glace de mer Abondance et diversité de poissons Couleur des océans

This dataset includes the data published in Goyens et al. (2018, DOI:10.1002/2017EA000332). It provides the following parameters for the different ice, snow and ponded ice stations of the GreenEdge Ice Camp 2015: - the hyperspectral (400-1000 nm) Hemispherical Directional Reflectance Factor (HDRF, units: dimensionless) measured with Analytical Spectral Device, Inc. (ASD) over a full hemisphere with 30° angular resolution along zenith and azimuth, - the hyperangular (full hemisphere at 1° angular resolution) multispectral (438, 560 and 628 nm) upwelling irradiance (Lu, units: µW.cm^-2.sr^-1.nm^-1) measured with a circular fish‐eye radiance camera (CE600) (median Lu and coefficient of variation are provided, see Goyens et al. (2018, DOI:10.1002/2017EA000332 for more info about data processing) - the multispectral (at 406.42, 434.48, 442.33, 489.70, 508.43, 560.22 and 624.20 nm) downwelling irradiance (Ed, units: µW.cm^-2.nm^-1) measured with the OCR from Satlantic, - the hyperangular HDRF (units: dimensionless) estimated as PI times the ratio of Lu CE600 to Ed OCR at 438, 560 and 628 nm (median and coefficient of variation are provided, see Goyens et al. (2018, DOI:10.1002/2017EA000332 for data processing), and, - the columnar aerosol optical depth (AOD, units: dimensionless) at 440, 500, 675, 870 and 936 nm estimated from a Handheld 5-channel Sunphotometer Microtops II.
