Great Lakes Mesoscale Boundary Database - TO2015 Pan and Parapan American Games

Great Lakes Mesoscale Boundary Database - TO2015 Pan and Parapan American Games Mesoscale boundaries have an important influence on mesoscale weather. They can trigger, enhance or inhibit convections and severe weather. They are also indicators of shifts in wind speed and direction, temperature and relative humidity, and can affect air quality and heat indices. Around the Great Lakes, it has been observed that mesoscale boundaries are prevalent and can have complex interactions between each other. A mesoscale boundary is the interface between two air masses for weather phenomenon on a scale of 5km to 100km. Mesoscale boundaries are generally associated with wind and differences in temperature, pressure and relative humidity. During the 2015 Pan Am and Parapan Am Games periods, boundary information were collected from July 10 to August 15, 2015. These included lake and land breeze fronts, outflow boundaries, as well as merged and other boundaries. Each mesoscale boundary is represented as a curve on the surface of the Earth with a list of coordinates. The data are stored in GeoJSON format and Shapefiles. A CSV file summarizes all the properties of the boundaries, but does not include any geometric information. 2021-07-27 Environment and Climate Change Canada open-ouvert@tbs-sct.gc.ca Nature and EnvironmentGreat Lakesmesoscale boundarydatabasegeodatabaselake and land breeze frontsoutflow boundariesshapefiles2015 Toronto Pan American and Parapan American GamesWeatherClimatologymeteorologyatmosphereWeather and Climate TO2015 Pan and Parapan American Games Science Showcase Research https://open.canada.ca/data/en/dataset/55c920ff-bc8d-4fd2-ad40-722d03ec97b5 TO2015 Pan and Parapan American Games Science Showcase Research https://ouvert.canada.ca/data/fr/dataset/55c920ff-bc8d-4fd2-ad40-722d03ec97b5 AllFiles_TousLesFichiers_PanAm2015.csvCSV https://data-donnees.ec.gc.ca/data/weather/scientificknowledge/to2015-pan-and-parapan-american-games-science-showcase-research/great-lakes-mesoscale-boundary-database-to2015-pan-and-parapan-american-games/AllFiles_TousLesFichiers_PanAm2015.csv MesoscaleFrontsPanam2015.gdb.7zFGDB/GDB https://data-donnees.ec.gc.ca/data/weather/scientificknowledge/to2015-pan-and-parapan-american-games-science-showcase-research/great-lakes-mesoscale-boundary-database-to2015-pan-and-parapan-american-games/MesoscaleFrontsPanam2015.gdb.7z Key_Dictionary_Dictionnaire_De_Clefs.csvCSV https://data-donnees.ec.gc.ca/data/weather/scientificknowledge/to2015-pan-and-parapan-american-games-science-showcase-research/great-lakes-mesoscale-boundary-database-to2015-pan-and-parapan-american-games/Key_Dictionary_Dictionnaire_De_Clefs.csv Value_Dictionary_Dictionnaire_de_Values.csvCSV https://data-donnees.ec.gc.ca/data/weather/scientificknowledge/to2015-pan-and-parapan-american-games-science-showcase-research/great-lakes-mesoscale-boundary-database-to2015-pan-and-parapan-american-games/Value_Dictionary_Dictionnaire_de_Values.csv English_to_French_Anglais_a_Francais.xlsXLS https://data-donnees.ec.gc.ca/data/weather/scientificknowledge/to2015-pan-and-parapan-american-games-science-showcase-research/great-lakes-mesoscale-boundary-database-to2015-pan-and-parapan-american-games/English_to_French_Anglais_a_Francais.xls ReadMe_PanAm2015.txtTXT https://data-donnees.ec.gc.ca/data/weather/scientificknowledge/to2015-pan-and-parapan-american-games-science-showcase-research/great-lakes-mesoscale-boundary-database-to2015-pan-and-parapan-american-games/ReadMe_PanAm2015.txt ReadMe_PanAm2015.txtTXT https://data-donnees.ec.gc.ca/data/weather/scientificknowledge/to2015-pan-and-parapan-american-games-science-showcase-research/great-lakes-mesoscale-boundary-database-to2015-pan-and-parapan-american-games/LizezMoi_PanAm2015.txt View ECCC Data Mart (English)HTML https://data-donnees.ec.gc.ca/data/weather/scientificknowledge/to2015-pan-and-parapan-american-games-science-showcase-research/great-lakes-mesoscale-boundary-database-to2015-pan-and-parapan-american-games/ View ECCC Data Mart (French)HTML https://data-donnees.ec.gc.ca/data/weather/scientificknowledge/to2015-pan-and-parapan-american-games-science-showcase-research/great-lakes-mesoscale-boundary-database-to2015-pan-and-parapan-american-games/?lang=fr
