Comparison of the nontransport processes that affect PM
In Shan et al., Top: CO2 emissions from seven cities in Tibet, 2014. The colors of the map show the per capita emissions (CO2 emissions/population, in tons) of each city. Greener cities have lower per capita emissions while redder cities have higher ones. The blue circlesrepresent emissions intensity (CO2 emissions/total GDP) for each city; larger circles refer to a higher emission intensity. The numbers on the map show the emission intensity of each city (in tons per thousand yuan); for example, the emission intensity of Lhasa is 0.84 tons per thousand yuan. Bottom: emissions from fossil fuel types and sectors in Tibet, 2014.
The estimated linkages of stream water quality with the land use and hydrologic drivers identify the management targets and priorities to achieve healthy coastal-urban stream ecosystems.

In Queißer et al. [10.1002/2017JB013968], snapshots of a bursting gas bubble of the main vent (vent II) at the Bledug Kuwu complex. The bursts had a duration of approximately ~2s.

Top row (a, b) shows surface radar reﬂ ectivity in dBZ, middle row (c, d) shows vertical cross section of line-averaged radar reﬂ ectivity, and bottom row (e, f) shows vertical cross section of line-averaged median drop diameter in mm.

In Chen et al. [DOI: 10.1002/2016JD026427], figure 1 shows schematic summary of the two mechanisms of interhemispheric transport:
Ceres has plenty of permanently shadowed regions (mapped in blue) at the present day when its obliquity is small. However, due to obliquity changes in the past, only few permanent shadows remain.
Case study of projected changes in rainfall on the Island of Maui, Hawaii, and associated estimates of changes in low flows. (a) Percentage change in average annual rainfall from statistical downscaling models [Timm et al., 2015] at ungaged basins between 1978–2007 and 2071–2099. (b) Percentage change in average annual rainfall from dynamical downscaling models [Zhang et al., 2012; APDRC, 2016] at ungaged basins between 1978–2007 and 2090–2109, Maui Hawaii. (c) Percentage changes in Q70k¯ associated with rainfall A computed using rainfall elasticity ( εx) values from random-effects panel regressions for ungaged basins and from streamflow records for gaging stations. (d) Percentage changes in Q70k¯ associated with rainfall B computed using εx values from fixed effects panel regressions for ungaged basins and from streamflow records for gaged basins. Basins without an estimate of changes in low flow are classified as nonperennial and streams in these basins do not have natural low flows for recent conditions. Some ungaged streams may be misclassified.
