In Forouta et al., the emission of particulate matter with diameter less than 10 microns (PM10) due to dust outbreaks over the southwestern United States in March 7, 2011 (top left), March 21, 2011 (top right), April 3, 2011 (bottom left), and May 29, 2011 (bottom right). The results (in gm-3) are obtained using a newly developed windblown dust scheme implemented in the Community Multiscale Air Quality (CMAQ) modeling system
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.
Temporal height distribution of the temperature deviation from 19 to 25 January 2008.
image shows (a) Map of hydraulic head in the floodplain aquifer across three sampling seasons.
SuperDARN and PFISR radar observations over the polar cap.
In Czuba et al. image shows Lidar hillshade highlighting major features (river, bluff, and ravine, each with relevant attributes) incorporated into the model. Inset image shows a 64m bluff; note the canoe for scale. Location and extent is shown in Figure3by a small red box.

The Ex-Alta 1 Cube-Satellite, to be launched in late 2016 as part of the ESA QB50 constellation mission, will demonstrate the potential
In Yanase et al., image shows time-longitude cross sections of the composite surface rain rate from TRMM 2A25 for (a) December, January, and February; (b) March, April, and May; (c) June, July, and August; and (d) September, October, and November
In Roman and Jaupart [10.1002/2016JB013912], the development of downwellings at the leading edge of the intrusion in two different experiments (nos. 1425 and 1427) in the jellyfish regime. The only difference between these two experiments is the intrusion volume, which varies by a factor of 5.6. All the other parameters are identical. This shows that the downwelling dimensions increase with the intrusion volume.
In Siebach et al. MAHLI image examples of each of the textural classes of rocks in the Bradbury group and (h) the Murray mudstone in the Mount Sharp group. White scale bars are 1 cm across. Classes were divided on the basis of grain size and/or surface texture and coloring and include (Figure 2a) Sheepbed mudstone (10 APXS analyses; example is Wernecke_preDRT, sol 168), exposed in Yellowknife Bay with grains finer than the limit of resolution; (Figure 2b) fine sandstone (15 APXS analyses; example is Aillik1, sol 322), well-sorted siltstones to sandstones; (Figure 2c) sandstone (22 APXS analyses; example is Gillespie_Lake, sol 132), medium to pebbly sandstones; (Figure 2d) conglomerate (15 APXS analyses; example is Bardin_Bluffs, sol 394), primary grain sizes >1 mm, rounded grains, clasts up to 6 cm; (Figure 2e) uncertain (13 APXS analyses; example is Morehouse, sol 503), float rocks with poorly defined grain boundaries, sometimes weather like conglomerates; (Figure 2f) possible igneous (4 APXS analyses; example is Clinton, sol 512), small group of float rocks and one clast in a conglomerate with porphyritic textures, shortened to “igneous” in plot legends; (Figure 2g) diagenetic (36 APXS analyses; example is CumberlandNewRP_LIBs, sol 277), rocks with clearly diagenetic textures including preferential cementation and fracture fills; and (Figure 2h) Murray mudstone (27 APXS analyses; example is Punchbowl2, sol 813), mudstone observed at
The south coast of Wellington (NZ), looking east from Baring Head, braces for the arrival of a dramatic cold front that delivered torrential rain and severe southerly gales to the city. Measuring, modelling and understanding the complexity of rainfall states and their temporal and spatial dynamics is at the core of research undertaken
by Sansom et al. (2017). They use a continuous-time rainfall model to better understand how well rainfall dynamics are preserved after aggregation into conventional time periods (minutes, hours, or days) and over different spatial scales. Credit: Katja Riedel, NIWA.
In Roesler et al., total condensate (precipitating rain and snow and nonprecipitating water and ice) and the vertical velocity at 12 h into the simulation for the (left) 1.5 TKE scheme and the (right) CLUBB scheme. The total condensate is shown in the rainbow color bar, and the vertical velocity is shown with the blue-to-red color bar.
In Crusius et al., (top left) Expanded map of sampling region. The map at right shows the sampling stations (green circles) on the shelf/slope transect extending seaward from near the mouth of the Copper River (AK) (Station 1) to beyond the shelf break (Station 5).

In Brown et al., idealized squall line experiments using (left column) M20Efrr and (right column) M75Efrr. 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.
Image shows ROV images of the hornitos at the summit of the Tagoro volcano: (a) Location on the images on the multibeam bathymetry from the 28 June 2012. (b) Deepest hornito formed by 4–5 m tall pyramid-like of agglutinated lava blocks intermixed with yellow hydrothermal deposits (115 m water depth). (c) Detail of degassing vents (yellow orifices) along the flanks of the chimney interpreted as active hydrothermal vents (118 m water depth). (d) Top of the shallowest “hornito” (89 m water depth) showing abundance of red flocculates covering the lava deposits. (e) Detail of the flank of a hornito showing white bacterial mats. (f ) Detail the tapestry of red to orange amorphous Fe-oxyhydroxide flocculates covering the overall summit of the Tagoro volcanic edifice.
In Rutte et al., image shows (a–d) Panoramic views of the Muskol dome. Distortion increases toward the image edges. Figures 4a and 4b are along section A in Figure 8. Thrusts and north vergent, recumbent, isoclinal folds in Figure 4d are in left part of Figure 4c.
