The models also serve to assist in the design of effective control strategies to reduce emissions of harmful air pollutants. During the late 1960s, the Air Pollution Control Office of the U.S. EPA initiated research projects that would lead to the development of models for the use by urban and transportation planners. [1]
The project aimed to use a nuclear engine in a supersonic cruise missile. It would operate at Mach 3, or around 3,700 kilometres per hour, be invulnerable to interception by contemporary air defenses, and carry up to sixteen with nuclear weapons with yields of up to 10 megatonnes of TNT.
This is a list of international environmental agreements. Most of the following agreements are legally binding for countries that have formally ratified them. Some, such as the Kyoto Protocol , differentiate between types of countries and each nation's respective responsibilities under the agreement.
The HYSPLIT model can be run interactively on the Real-Time Environmental Applications and Display System (READY) web site [12] or installed on PC, Mac, or Linux applications, which use a graphical user interface, or automated through scripts ('PySPLIT' package in Python, 'openair' and 'splitr' packages in R). HYSPLIT is rather unusual in that ...
The Environmental Protection Act of 1990 established the system of Integrated Pollution Control(IPC). Currently [ when? ] the clean up of historic contamination is controlled under a specific statutory scheme found in Part IIA of the Environmental Protection Act 1996 (Part IIA), as inserted by the Environment Act 1995, and other ‘rules ...
There are five types of air pollution dispersion models, as well as some hybrids of the five types: [1] Box model – The box model is the simplest of the model types. [2] It assumes the airshed (i.e., a given volume of atmospheric air in a geographical region) is in the shape of a box.
Project Pluto was a United States government program to develop nuclear-powered ramjet engines for use in cruise missiles. Two experimental engines were tested at the Nevada Test Site (NTS) in 1961 and 1964 respectively.
It would then have the option of using Charon's gravity to leave the Pluto system after all Pluto science objectives are completed and study new KBOs beyond Pluto. Stern envisaged the probe being launched in 2030, marking the 100th anniversary of Pluto's discovery, and spending 7–8 years traveling to the Pluto system.
