Data used in the study correspond to two datasets.-- Last update has been done in February 2019., [Flux_data.xls] Fluxes of PM in rain, throughfall and stemflow for two tree species (Quercus pubescens Willd. and Pinus sylvestris L.) from June 2015 to June 2016. In this file, no available data is indicated as “NA”. Data structure: • Date: Date of the sample collection • Rain flux: Particulate matter flux in rain (in mg m-2). • Th_Oak_flux: Particulate matter flux in throughfall for Quercus pubescens Willd. (in mg m-2). • Th_Pine_flux: Particulate matter flux in throughfall for Pinus sylvestris L. (in mg m-2). • Sf_Oak_flux: Particulate matter flux in stemflow for Quercus pubescens Willd. (in mg m-2). • Sf_Pine_flux: Particulate matter flux in stemflow for Pinus sylvestris L. (in mg m-2). • Rainfall: Accumulated rainfall between sampling days (in mm). • Origin: Air trajectory coming from: East, West or South. Calculated through 5-day backward trajectories using the HYSPLIT model (Rolph et al., 2017; Stein et al., 2015)., [Filters_data.xlsx] Results from the examination of filters of rainfall, throughfall and stemflow for both species and for 7 events. Data comes from a Zeiss LSM 510 Meta-5 Live Duo confocal microscope and a post processing made with ImageJ. The confocal microscopy analyses have been conducted at the BioImaging Centre at the University of Delaware. Data structure: Area: Area of particles (μm2). Perim.: Perimeter, length of the outside boundary of the particle (μm). Major: Primary axis of the best fitting ellipse (μm). Minor: Secondary axis of the best fitting ellipse (μm). Angle: Angle between the primary axis and a line parallel to the X-axis of the image (º). Circ.: Circularity 4π·([Area])/〖[Perimeter]〗^2 with a value of 1.0 indicating a perfect circle. As the value approaches 0.0, it indicates an increasingly elongated shape. Feret: Feret diameter, the longest distance between any two points along the selection boundary, also known as maximum caliper (μm). FeretAngle: The angle (0 - -180 degrees) of the Feret’s diameter (º). MinFeret: The minimum caliper diameter (μm). AR: Aspect ratio, the aspect ratio of the particle’s fitted ellipse, i.e., ([Major Axis])/([Minor Axis]) Round: Roundness, 4·([Area])/(π · 〖[Major axis]〗^2 ) or the inverse of Aspect Ratio. Solidity: ([Area])/([Convex Area]) Date: Date of the sampling. Type: Corresponding water flux. Rainfall (Rf), throughfall pines (Th_Pine), throughfall oaks (Th_Oak), stemflow pines (Sf_Pine) and stemflow oaks (Sf_Oak)., Particulate matter fluxes in a Mediterranean mountain forest: inter-specific differences between throughfall and stemflow in oak and pine stands. This project analyses the redistribution of water and particulate matter (PM) below forested areas in the Vallcebre research catchments during rainfall events. Data to analyse PM fluxes and diameter and shape distribution of PM has been produced by: Carles Cayuela, Delphis F.
