Description

The PM10.dat data frame is a subset of data analyzed in Hamm et al. (2015) and Datta et al. (2016). Data comprise April 6, 2010 square root transformed PM10 measurements across central Europe with corresponding output from the LOTOS-EUROS Schaap et al. (2008) chemistry transport model (CTM). CTM data may differ slightly from that considered in the studies noted above due to LOTOS-EUROS CTM code updates. A NA value is given at CTM output locations were PM10 is not observed. Point coordinates are in "+proj=laea +lat_0=52 +lon_0=10 +x_0=4321000 +y_0=3210000 +ellps=GRS80 +units=km +no_defs".

Usage

Format

Columns for PM10.dat:

• x.coord = x coordinate (see projection information in the description)

• y.coord = y coordinate (see projection information in the description)

• pm10.obs = square root transformed PM10 measurements at monitoring stations (NA means there is not a station at the given location)

• pm10.ctm = square root transformed PM10 from CTM
