Staying Within Budget: Carbon Planning
While we usually concern ourselves with budgeting money or time, we should be thinking about another type of budget: the carbon budget. The carbon budget refers to the amount of carbon exchange, especially carbon dioxide, allotted on an annual basis to prevent the earth from reaching an increase of 2-degrees Celsius all over the globe. If a 2 degree increase does occur, global warming effects are expected to be catastrophic and irreversible . 
 
In order to know how close we are to reaching the carbon budget, an extensive knowledge of types of carbon input and their magnitudes, as well as their fluctuations over time, is needed.

Determining exchange rates of carbon dioxide between the earth’s forests and the atmosphere is turbulent business. 
 Wind above forest canopies swirls as vortexes of air enter and exit stands of trees. Across the globe, towers stand among the landscape, with sensors monitoring these eddies for carbon dioxide, water vapor and other gasses. These so-called “flux towers” collect data on carbon dioxide exchange rates between the earth and atmosphere. 
 Information gathered plays into the debate on the measurable effects of climate change. 
 Carbon dioxide flows between the earth, atmosphere and ocean in an attempt to reach equilibrium. As automobiles and energy production facilities burn fossil fuels, more carbon dioxide joins to the mix.

The Onset HOBO RX3000 Remote Monitoring Station is an environmental monitoring system that continuously logs data from compatible sensors that measure soil moisture, water level, temperature and various weather parameters. With numerous options for remote monitoring systems, Onset provides a Build-a-system configurator to help with ordering a system fit for any project’s needs. The configurator easily guides the user through the process of selecting different types of communication, power, sensor and other site-specific requirement selections when building their ideal system. 
 
 The RX3000 ships with mounting plates and hardware, rubber cable channels, rubber plugs, grease, grounding wire and U-bolts.
