English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
  • Atmospheric Physics
CONT

To produce the UV index forecast, Environment and Climate Change Canada takes data from ozone measuring stations across the country to determine the present thickness of the ozone layer. A computer model then forecasts the thickness of the ozone layer over Canada for the next day. Combining the forecast of the ozone layer with data about the height and the angle of the sun gives a UV forecast for the next day, for a clear sunny sky. Adding the amount of cloud predicted in the weather forecast then gives the amount of UV that can actually be expected. The forecast gives the maximum amount of UV expected for the day. On a clear day with no clouds, this occurs at noon(or 1 p. m. for those on daylight time), when the sun is highest in the sky.

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
  • Physique de l'atmosphère
CONT

Pour établir les prévisions de l'indice UV, Environnement et Changement climatique Canada utilise les données provenant des stations de mesure de l'ozone réparties dans l'ensemble du pays afin de déterminer l'épaisseur de la couche d'ozone. Un modèle informatique prévoit ensuite l'épaisseur de la couche d'ozone partout au Canada, pour le lendemain. La combinaison des prévisions concernant la couche d'ozone et des données relatives à la hauteur et à l'angle du soleil fournit une prévision de l'indice UV pour le lendemain, pour du temps dégagé et ensoleillé. On y ajoute la couverture nuageuse selon les prévisions météorologiques, ce qui permet de calculer la quantité de rayons UV prévue. La prévision indique la quantité maximale de rayons UV prévue pour la journée. Par temps dégagé sans nuages, celle-ci est atteinte à midi (ou à 13 h à l'heure avancée), lorsque le soleil est à son zénith.

Subject field(s)
  • Orbital Stations
  • Research Experiments in Space
OBS

The Astro/PGBA [Astro/plant generic bioprocessing apparatus] experiment hardware is contained in a double locker that will be installed into the EXPRESS Rack after the Shuttle is in orbit. The hardware consists of a plant growth chamber with a 10-inch by 12-inch growth area that allows 10 inches of plant height and 2 inches of roots. Fluorescent or LEO lighting will simulate sunlight, and an atmospheric control system will maintain set levels of carbon dioxide and humidity while scrubbing volatile organic compounds, such as ethylene, that can accumulate and inhibit plant growth. Plant transpiration water, collected from a dehumidifier system, can be recirculated back into the root matrix. A computer system will control experiment operations and provide engineering and video data for downlink to investigators on the ground.

OBS

The PGBA has successfully supported plant experiments that examine changes in plant lignification and related downstream biochemical consequences, especially production of secondary metabolites.

OBS

astro/plant biogeneric processing apparatus: term officially approved by the International Space Station official approval Group (ISSOAG).

directional wave spectrum: A two-dimensional spectrum that shows how the wave energy is distributed between various directions of incidence, in addition to how it is distributed among various frequencies.

OBS

Spectres directionnels. - La forme des spectres en fréquence est encore le sujet de discussions […] en particulier dans sa partie haute fréquence qui est très importante pour la réflexion d’ondes radar [...] Pour la forme directionnelle des vagues les incertitudes sont bien plus grandes, même au niveau du pic spectral, en particulier à cause du faible nombre d’observations directionnelles de bonne qualité. Le spectre fréquence-direction [...] se décompose de manière usuelle [...]

OBS

Les bouées de mesures du spectre directionnel des vagues (pilonnement, roulis, tangage, cap) ont deux avantages importants par rapport aux autres instrumentations possibles : elles sont utilisables quelle que soit la profondeur d'eau en dehors de la zone littorale de déferlement, et elles fournissent une information continue en fréquence sur tout le spectre de vagues de périodes supérieures à 2.5 secondes.

D. B. Turner(1961) introduced a version of Pasquill' s scheme in which the incoming solar radiation is classified in terms of elevation angle, cloud amount and cloud height. This stability classification system has been made completely objective so that an electronic computer can be used to compute stability classes. The stability classes proposed by Turner are as follows : A=extremely unstable; B=unstable; C=slightly unstable; D=neutral; E=slightly stable; F=stable, and G=extremely stable.
