Near-Surface Wind
Near-surface wind is one of the most important meteorological parameters. Near-surface wind grid products are an important part of live analysis products . Reliable near-surface wind products have an important role in the monitoring, prediction, and study of wind disasters. The evaluation of near-surface wind products can provide the direction for improving the data quality for Hainan, provide basic support for fine-grid forecasting and meteorological services, and help to reduce the losses that are caused by wind disasters.

Two Medicine Formation
The Two Medicine Formation is a geological formation, or rock body, in northwestern Montana and southern Alberta that was deposited between 83.5 ± 0.7 Ma and 70.6 ± 3.4 Ma (million years ago), during Campanian (Late Cretaceous) time. It crops out to the east of the Rocky Mountain Overthrust Belt, and the western portion (about 600 metres or 2,000 feet thick) of this formation is folded and faulted while the eastern part, which thins out into the Sweetgrass Arch, is mostly undeformed plains. Below the formation are the nearshore (beach and tidal zone) deposits of the Virgelle Sandstone, and above it is the marine Bearpaw Shale. Throughout the Campanian, the Two Medicine Formation was deposited between the western shoreline of the Late Cretaceous Interior Seaway and the eastward advancing margin of the Cordilleran Overthrust Belt. The Two Medicine Formation is mostly sandstone, deposited by rivers and deltas.

Ectomycorrhizal Mushrooms
Environmental changes and heavy metal pollution are some of the consequences of anthropogenic activities. Many ecosystems, including edaphic ecosystems, suffer from the effects of pollution. The accurate assessment of soil heavy metal contamination leads to better approaches for remediating soils. The exploration of different ways, including biological methods, to conduct environmental monitoring is still ongoing.

Tungsten in Soil
Tungsten (W) occurs naturally in soils and the Earth’s crust is the most important source of this element. Tungsten reserves have been estimated to be approximately 3.1 Mt in ore deposits, where the metal exists mainly as a component of several minerals, such as wolframite (Fe, MnWO4) and scheelite (CaWO4).

September 1859 Geomagnetic Storm
The September 1859 geomagnetic storm (also known as the Carrington Event) was a powerful geomagnetic storm during solar cycle 10 (1855–1867). A solar coronal mass ejection (CME) hit Earth's magnetosphere and induced the largest geomagnetic storm on record on September 1–2, 1859. The associated "white light flare" in the solar photosphere was observed and recorded by British astronomers Richard C. Carrington and Richard Hodgson. The storm caused strong auroral displays and wrought havoc with telegraph systems. The now-standard unique IAU identifier for this flare is SOL1859-09-01. A solar storm of this magnitude occurring today would cause widespread electrical disruptions, blackouts and damage due to extended outages of the electrical grid. The solar storm of 2012 was of similar magnitude, but it passed Earth's orbit without striking the planet, missing by nine days.

Physical, Chemical, and Environmental Properties of Phthalates
Phthalic acid esters (PAEs), commonly named phthalates, are a class of dialkyl or alkyl/aryl esters of phthalic acid (1,2-benzenedicarboxylic acid) structured in one benzene ring linked with two aliphatic ester groups, most commonly in the ortho configuration.

Female Fertility and Environmental Pollution
Terrestrial ecosystems are contaminated by heavy metals and organic chemicals that can be taken up by and accumulate in crop plants, and water tables are heavily contaminated by untreated industrial discharges. As deadly particulates can drift far, poor air quality has become a significant global problem and one that is not exclusive to major industrialized cities. The consequences are a dramatic impairment of our ecosystem and biodiversity and increases in degenerative or man-made diseases. In this respect, it has been demonstrated that environmental pollution impairs fertility in all mammalian species. The worst consequences are observed for females since the number of germ cells present in the ovary is fixed during fetal life, and the cells are not renewable. This means that any pollutant affecting hormonal homeostasis and/or the reproductive apparatus inevitably harms reproductive performance.

Services Accessibility in Rural Areas
The accessibility of services in rural areas can be considered to be one of the most important aspects of the creation of comparable living conditions in the whole territory of Europe. The inaccessibility of services can be considered an important factor of rural deprivation.

Canadian Arctic Archipelago
The Canadian Arctic Archipelago, also known as the Arctic Archipelago, is a group of islands north of the Canada mainland. Situated in the northern extremity of North America and covering about 1,424,500 km2 (550,000 sq mi), this group of 36,563 islands in the Arctic Sea comprises much of the territory of Northern Canada – most of Nunavut and part of the Northwest Territories. The Canadian Arctic Archipelago is showing some effects of global warming, with some computer estimates determining that melting there will contribute 3.5 cm (1.4 in) to the rise in sea levels by 2100.
