We demonstrate the use of the open source library GeoTemCo for the visualization and exploration of geospatialtemporal datasets from environmental sciences. With use cases from biodiversity, climatology and geophysics we investigate the capabilities and limitations of GeoTemCo, which types of research questions can be handled and how the observer is able to gain new insights about the given data.

Our primary source for climate data is the Terrestrial Air Temperature and Precipitation: 19002006 Gridded Monthly Time Series, Version 1.01 (2007), compiled by Kenji Matsuura and Cort Willmott in conjunction with NASA. The data are available at http://climate.geog.udel.edu/ ~climate/html_pages/download.html. This dataset combines station data on mean air temperature and precipitation from a nu...

This paper reports initial results from an Ozone Mapping and Profiler Suite (OMPS) Nadir Mapper cloud pressure and cloud fraction algorithm. The OMPS cloud products are intended for use in OMPS ozone or other tracegas algorithms. We developed the OMPS cloud products using a heritage algorithm developed for the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite. The cloud pressure algori...

The Eastern Tropical and Subtropical Pacific, particularly the coastal region of the western South America, is affected by the El Niño Southern Oscillation (ENSO) event. In this work ERS-1 and ERS-2 scatterometer data of wind stress climatology are used to study Ekman pumping/suction and transport in the coastal ocean at 15°S off San Juan, Peru. The Princeton Ocean Model (POM) was run to study ...

Extreme weather events such as ice storms cause significant damage to life and property. Accurately forecasting ice storms sufficiently in advance to offset their impacts is very challenging because they are driven by atmospheric processes that are complex and not completely defined. Furthermore, such forecasting has to consider the influence of a changing climate on relevant atmospheric variab...

The notion of m-regular system on the Hermitian variety H(n, q2) was introduced by B. Segre (Ann. Math. Pura Appl. 70:1–201, 1965). Here, three infinite families of hemisystems on H(5, q2), q odd, are constructed.

Analysis of the long-term Global Aerosol Climatology Project data set reveals a likely decrease of the global optical thickness of tropospheric aerosols by as much as 0.03 during the period from 1991 to 2005. This recent trend mirrors the concurrent global increase in solar radiation fluxes at Earth's surface and may have contributed to recent changes in surface climate.

Determining the factors that influence the distribution of woody vegetation cover and resolving the sensitivity of woody vegetation cover to shifts in environmental forcing are critical steps necessary to predict continental-scale responses of dryland ecosystems to climate change. We use a 6-year satellite data record of fractional woody vegetation cover and an 11-year daily precipitation recor...

In the last three decades we have experienced the first close-up exploration of the planets of the solar system. American, Russian, and (increasingly) European planetary space missions have now explored the atmospheres and environments of many different worlds, returning data with which we can begin to understand the Earth in its wider context as never before. The new discipline of Comparative ...

Clouds are essential for life to exist on earth due to their influential climatological impact. Clouds help control the radiation balance of the earth by reflecting incoming solar radiation, a cooling process; however, clouds also act as absorbers of terrestrial infrared radiation, a warming process. This dual role is a primary motive to examine the effects clouds have on the global climate. Qu...
