title: Winter Season Spectral Snowpack Albedo Data For the Caldor and Creek Fires

description: * Description: The file "Caldor_Creek_Fires_Winter_Snow_Albedo_Spectrometer_Dataset.csv" is a comma-delimited file containing the spectral snowpack albedo measurements from the Caldor and Creek Fires in California and the associated burn severities at the location of each measurement. Data and File Overview ====================== Summary Metrics --------------- * File count: 1 * Total file size: 909 KB * Range of individual file sizes: 909 KB * File formats: .csv Naming Conventions ------------------ * File naming scheme: One file that includes all dates, all burn severities, all wavelengths. * Format(s): Comma-separated value (.csv) file * Size(s): 909 KB * Dimensions: 17,209 rows x 6 columns * Variables: * Measurement_Number: An index of the measurement number, unitless * wavelength: The wavelength of light (units in nanometers) for which albedo sample ranging from 350-2500 nm * Type: Measurement type is albedo in various burn severity environments (_hb is high burn severity, _mb is moderate burn severity, _ub is unburned, with the last letter corresponding to the month (J is January, F is February, A is April). NA corresponds to estimated January unburned data for the Caldor Fire where unburned albedo for April in the Creek Fire was adjusted downwards by 0.04 to account for less grain-size growth (Colbeck 1982, Rev. Geophys., https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/RG020i001p00045). * Albedo: The albedo (unitless), is a measurement of the solar radiation reflected by the snow surface divided by the radiation incident on its surface. In other words, albedo is the fraction of the incident sunlight reflected by the snow. * month: The month when the measurement was taken * burn: Burn severity at measurement location based upon classifications (High, Medium,, Unburned) from the Monitoring Trends in Burn Severity Dataset (https://mtbs.gov/). NA corresponds to the estimated unburned data for the Caldor Fire using April unburned data in the Creek Fire. * Missing data codes: No missing data is presented. Dates and Locations ------------------- * Dates of data collection: Surface albedo collected in 27-28 February 2021, 1 April 2021, and 21 January 2022 * Geographic locations of data collection: Data collected within the Caldor Fire perimeter in the central Sierra Nevada, California-Nevada (January 2022) and the Creek Fire perimeter, California (February and April 2021). Setup ----- * Recommended software/tools to open file: parentage- R Studio; file can be opened using any text editor or programming language (e.g., R Studio, MATLAB, Python, TextMate, Microsoft Excel, etc)
