Soil database from wildfires areas in Aragón (Spain): laboratory properties and spectral data

Soil database from wildfires areas in Aragón (Spain): laboratory properties and spectral data. This dataset contains information from 127 soil samples collected across 20 forest areas distributed throughout Aragón (Spain). The samples correspond to the top 5 cm of soil, obtained from both burned areas affected by wildfires and their corresponding control areas. The database integrates two types of information: - Soil properties (texture, fertility, non-silicate minerals and exchangeable cations) determined at the Agro-Environmental Laboratory of the Government of Aragón. - Spectral signatures expressed as reflectance values (biconical reflectance factor). Spectral data were acquired using an ASD FieldSpec 4 SR spectrometer, covering the 350–2500 nm range (visible to short-wave infrared) with 1 nm spectral interval and 3 to 10 nm spectral resolution. Measurements were taken under controlled laboratory illumination conditions with a contact probe on air-dried and sieved (<2 mm) soil samples.
