Ultraviolet Radiation Sensor
- Manufacturer: SGLUX
- Model: UV-Cosine
- Info: Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, that is, in the range between 400 nm and 10 nm, corresponding to photon energies from 3 eV to 124 eV. It is so-named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet. These frequencies are invisible to humans, but near UV is visible to a number of insects and birds. The ultraviolet index or UV Index is an international standard measurement of the strength of the ultraviolet (UV) radiation from the sun at a particular place on a particular day.
Solar Radiation Sensor
- Manufacturer: Apogee Instruments
- Model: SQ-215
- Info: Photosynthetically active radiation, often abbreviated PAR, designates the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of photosynthesis. This spectral region corresponds more or less with the range of light visible to the human eye. Photons at shorter wavelengths tend to be so energetic that they can be damaging to cells and tissues, but are mostly filtered out by the ozone layer in the stratosphere. Photons at longer wavelengths do not carry enough energy to allow photosynthesis to take place.
- Manufacturer: Vaisala
- Model: WXT520
- Info: The Vaisala Weather Transmitter WXT520 measures barometric pressure, humidity, precipitation, temperature, and wind speed and direction.
Barometric pressure is the weight of the overlying air pressing down on the Earth, it is usually reported in milibars and the average sea level pressure is 1013.25 mbar. Generally, high pressure (~ 1040 mbar) supports sunny, clear weather. Low pressure (~ 950 mbar) promotes rainy and cloudy weather conditions. Big changes in barometric pressure indicate big changes in weather.
Relative humidity is the ratio, of the amount of moisture present in the air to the total amount of moisture that the air can hold at the same temperature.
Precipitation is presented in two differents parameters, rain intensity and rain amount. Rain is ligth when its intensity is < 2.5 millimetres per hour (mm/h) and heavy when is > 7.6 mm/h. Rain amount quantifies the precipitacion accumulated during a month.
Wind speed describes how fast the air is moving past a certain point at a certain time and wind direction describes the direction on a compass from which the wind comes. Wind direction is displayed in degrees where 180º means the wind is coming from south, 90º East, 270º West and 360º North.
