Most of the ozone production occurs in the tropical upper stratosphere and mesosphere. The total mass of ozone produced per day over the globe is about 400 million metric tons. The global mass of ozone is relatively constant at about 3 billion metric tons, meaning the Sun produces about 12% of the ozone layer each day. [1]
It has been determined that the ozone decomposition follows a first order kinetics, and from the rate law above it can be determined that the partial order respect to molecular oxygen is -1 and respect to ozone is 2, therefore the global reaction order is 1. The ozone decomposition consists of two elementary steps: The first one corresponds to ...
Ozone in the troposhere is determined by photochemical production and destruction, dry deposition and cross-tropopause transport of ozone from the stratosphere. [2] In the Arctic troposphere, transport and photochemical reactions involving nitrogen oxides and volatile organic compounds (VOCs) as a result of human emissions also produce ozone resulting in a background mixing ratio of 30 to 50 ...
The largest Antarctic ozone hole recorded (September 1985) 2012 retrospective video by NASA on the Montreal Protocol. The Montreal Protocol on Substances That Deplete the Ozone Layer [2] is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion ...
On Friday, the Park Fire became the fourth-largest wildfire in California history. Now at 401,301 acres, the blaze surpassed the 2020 SCU Lightning Complex fire that torched 397,000 acres across ...
The Park Fire, as of Monday afternoon, has burned a total of 370,237 acres (578 square miles), and 12% of the wildfire had been contained, according to Cal Fire. The fire has burned more than ...
Ground-level ozone (O 3), also known as surface-level ozone and tropospheric ozone, is a trace gas in the troposphere (the lowest level of the Earth's atmosphere), with an average concentration of 20–30 parts per billion by volume (ppbv), with close to 100 ppbv in polluted areas.
Wild videos showed the unoccupied Infiniti QX56 exploding into bright orange flames while parked on 133 Street in South Ozone Park around 6:45 a.m.. There were several lithium batteries inside the ...
