Abstract:
Particulate matter (PM) was analysed for four Dr.FOREST VIPs in Summer 2021. Sampling was carried out according to the Sampling Protocol of Task4 Dr.Forest (take a look for in-depth information). Based on "Dr_Forest_befdata_workbook_PM_2021" a particle size analysis was carried out prior to the gravimetrical particulate matter fractionation and mass analysis. For this task we used a Shimadzu SALD-2300 particle size analyser utilizing laser diffraction to analyse the particle size distribution the particulate matter deposition leaf sample solutions. We conducted a number-based and volume-based analysis of the same PM solution samples. We used the volume-based approach to capture the full distribution spectrum of the respective sample. As a downside of this method, a few big and voluminous particles can cover and mask smaller particles on the leeward side of the laser beam. For that reason, we used a second methodological approach, the number-based analysis to measure very small particles
≤ 1 μm. The instrument gathers and stores all necessary information in a single sample run, making it possible to switch between those four method-approaches retrospectively. This file contains the number based analysis.
Design:
Sampling occured along a 1, 2, 3 and 4 species gradient.
Spatial extent:
B-Tree (Austria), FORBIO_Gedinne (Belgium), Orphee (France), BioTree (Germany)
Temporal extent:
Leaf sampling for the following sites happened on: BTREE: 23rd July 2021; FORBIO_Gedinne: 8th September 2021; Orphee: 23rd July 2021; Biotree 12th November 2021

Measurement cirumstances:
For leaf sampling for particulate matter determination an accumulation period without precipitation was necessary. The accumulation days are given in the data. For more information, contact the dataset owner
