Observations of Noctilucent Clouds from Denmark during 2011
type: Dataset
description: Observations of noctilucent clouds include images in the jpg format and a summary of their occurrence during summer season from the end of May to the middle of August. The time intervals between taken images are as follows: 3 min is from 20 May until 9 June; 1 min is from 10 June until 24 July; this is a high NLC season; 3 min is from 25 July until 15 August. Images for a given night are contained in a single folder. The name of the folder corresponds to the first date of a given night, i.e., 2011-06-01 is for the night 01/02 June 2011. The data is divided into three zip packages, after collection period, and a zip package with readme file and excel file. Images for a given night are contained in a single folder. The name of the folder corresponds to the first date of a given night, i.e., 2011-06-01 is for the night 01/02 June 2011.

PARTICULATE MATTER
type: DefinedTerm
description: 'Particulate matter,' also known as particle pollution or PM, is a complex mixture of extremely small particles and liquid droplets. Particle pollution is made up of a number of components, including acids (such as nitrates and sulfates), organic chemicals, metals, and soil or dust particles.The size of particles is directly linked to their potential for causing health problems. EPA is concerned about particles that are 10 micrometers in diameter or smaller because those are the particles that generally pass through the throat and nose and enter the lungs. Once inhaled, these particles can affect the heart and lungs and cause serious health effects. EPA groups particle pollution into two categories: - 'Inhalable coarse particles,' such as those found near roadways and dusty industries, are larger than 2.5 micrometers and smaller than 10 micrometers in diameter. - 'Fine particles,' such as those found in smoke and haze, are 2.5 micrometers in diameter and smaller. These particles can be directly emitted from sources such as forest fires, or they can form when gases emitted from power plants, industries and automobiles react in the air.
