GIS Professional Portfolio for William Thoman

Portfolio Overview The following professional portfolio demonstrates the use of Geographic Information Systems and associated fields such as remote sensing, computer programming, and spatial statistics in order to explore environmental and human phenomena and the interactions between humanity and the environment. The following projects transition from more narrowly focused remote sensing or spatial statistics projects to those which combine a number of skills and knowledge base

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

Sea Level Variability and Change

Land surface albedo represents the fraction of solar radiation scattered backward by land surfaces. In the presence of vegetation, surface albedo results from complex nonlinear radiation transfer processes determining the amount of radiation that is scattered by the vegetation and its background, transmitted through the vegetation layer, or absorbed by the vegetation layer and its background. Anomalies in mid- and high latitude regions of the Northern Hemisphere result mainly from interannual variations in snow cover extent and duration in winter and spring. The large negative anomalies over the United States reflect the lack of snowfall and snowpack over the Rockies, the Midwest, and much of the eastern half of the country.JRC.H.7-Climate Risk Managemen
