CLASS simulations for ALMIP2 (AMMA Land surface Model Intercomparison Project, Phase 2)

This dataset consists of CLASS (Canadian Land Surface Scheme) simulations for ALMIP2 (AMMA [African Monsoon Multidisciplinary Analysis] Land Surface Model Intercomparison Project, Phase 2). The results of the intercomparison is published in the paper "Streamflows over a West African Basin from the ALMIP2 Model Ensemble" (http://journals.ametsoc.org/doi/full/10.1175/JHM-D-16-0233.1).

Output files from the simulations contain variables for surface and sub-surface state, evaporation, water and energy balance and other hydrological processes for the ALMIP2 study area covering Benin, Niger and Mali in West Africa over the years 2005 to 2008.

The AMMA project was organized with the main goal of obtaining a better understanding of the intraseasonal and interannual variability of the West-African monsoon. Land-atmosphere coupling is expected to be significant in this region, so a high priority goal of AMMA is to better understand and model the influence of the spatiotemporal variability of surface processes on the atmospheric circulation patterns and the regional water cycle.

ALMIP2 deals with the local to mesoscales. Participating land surface, vegetation and hydrological models are evaluated and inter-compared in order to identify key processes which are not well modeled over this region, and to offer guidelines for future model development.

Egbert, Ontario - Non-Methane Hydrocarbons (NMHC) Study

The Continuous Non-Methane Hydrocarbon (NMHC) Measurements Study was a measurement program carried out at the Centre for Atmospheric Research Experiments (CARE) at Egbert, ON. Approximately 30 C2 to C8 hydrocarbons were collected and analyzed every three hours by an automated, in-situ gas chromatograph system. Data were collected continuously since from March, 2001 to February 2011. The objectives of the  study were to collect speciated hydrocarbon data for assessing clean and polluted air masses that arrive at the site to track long term trends in of NMHC mixing ratios in this quickly developing rural area to provide input for chemical transport models and other special studies carried out at the site, and to provide a long term intercomparison data set with co-located NMHC canister sampling carried out every third day by the National Air Pollution Surveillance Network (NAPS).

Automated Mobile Meteorological Observing System (AMMOS) - TO2015 Pan and Parapan American Games

Three hybrid vehicles equipped with AMMOS units were deployed during the 2015 Pan Am and Parapan Am Games as part of the high-resolution atmospheric monitoring network, the Mesonet, built by Environment and Climate Change Canada (ECCC) in support of the Games. AMMOS vehicles travelled prescribed routes (often simultaneously) between the Lake Ontario shore in Toronto and suburban/rural areas to the north and west. These three mobile stations collected data in locations where fixed stations cannot, such as along roadways surrounded by large buildings in downtown Toronto known as “urban canyons.” 

The AMMOS units collected temperature and humidity (aspirated), pressure, wind speed and direction, GPS location and vehicle speed, insolation, and black globe temperature at one-second intervals. The AMMOS vehicles also carried fine particulate air quality sensors, and one AMMOS vehicle carried a prototype AirSENCE air quality sampling system. Note that the Legacy Archive dataset only provides quality-controlled meteorological data averaged at 1-minute intervals. Other data may be obtained by contacting the lead scientist.

The AMMOS mobile observations complemented those from the Mesonet, helped monitor weather and air quality conditions during the Games, and thoroughly sampled lake-breeze fronts for study post-Games. Three summer students and 6 ECCC scientists operated the 3 vehicles, mostly in pairs (1 student with 1 scientist). Nearly 10 000 km were travelled over 22 intensive observation days.

Air Quality Model Data - TO2015 Pan and Parapan American Games

Environment and Climate Change Canada's (ECCC’s) air quality model, Global Environmental Multiscale – Model of Atmospheric Chemistry (GEM-MACH v2), was run at high spatial resolution to generate daily forecasts for the Air Quality Health Index (AQHI) at Pan Am sporting venue locations and for surface air quality measurement stations across the Greater Toronto Area.  The model was run for a domain covering all of Southern Ontario at a spatial resolution of 2.5-km grid spacing. The model also included updated traffic pollutant emissions, generated before the Games by using a road link-based, traffic flow model. The GEM-MACH model generated daily forecasts on an hourly interval and forecasts were available at 6am local time each morning.  Numerous chemical pollutants were predicted including ozone, nitrogen dioxide, carbon monoxide, sulfur dioxide, particulate matter, among others. The air quality forecasts were placed on several data servers for dissemination (ECCC Air Quality Model experimental website, Science and Technology ECPASS website, WISDOM health information website, MSC XM-Tools website, University of Toronto AirSensor website).  The data in the archive is for the high resolution GEM-MACH v2 demonstration model and is not the operational air quality forecast disseminated by the Canadian Meteorological Centre. The demonstration forecast archived here has not been corrected using the post-processing UMOS tool, a statistical algorithm based on previous model/observations correlations for a location.


A chemical objective analysis was also performed using the 2.5km GEM-MACH v2 model output and the surface observations within the model domain. The analysis is a fusion of the model and observations resulting in an improved model forecast surface map.

Image Analysis Ice Charts

The Canadian Ice Service acquires Synthetic Aperture Radar Satellite imagery in order to have data available for the provision of ice information. Upon request of specific clients, Synthetic Aperture Radar imagery will be analysed in more detail than for the daily ice charts and these image analysis usually available to the public.  The area covered by the image analysis coincides with an area related to the satellite path. The path of the satellite changes each day so the chart area shifts from one day to the next. The usual width of the satellite data collection for ice information is about 500 kilometres. At the Canadian Ice Service, we use 100 metre resolution.

When analysing the satellite imagery, the analyst takes into consideration other data such as optical satellite imagery and visual observations from ship and aircraft. The analysis of these images is particularly challenging in conditions such as when seas are rough or if water is on the ice either from melt or rainfall.

Ice conditions are described using the International Standard Ice Code. The code describes the ice in terms of total and partial concentrations, the stages of development and form of the four main ice types present.

Ice Thickness Program Collection, 2002-

The Ice Thickness Program Collection contains ice thickness and snow depth measurements for 11 sites. Measurements are taken at approximately the same location every year on a weekly basis, starting after freeze-up when the ice is safe to walk on, and continuing until break-up or when the ice becomes unsafe. The location is selected close to shore, but over a depth of water which will exceed the maximum ice thickness.

TO2015 Pan and Parapan American Games Science Showcase Research

The Pan and Parapan American Games are a regional international summer sporting event, staged every 4 years in the year prior to the Summer Olympic and Paralympic Games. The 2015 Games were awarded to Canada on November 6, 2009, by the Pan American Sports Organization.  The XVII Pan American Games and the V Parapan American Games were held in Toronto, Canada, from July 10–26, 2015, and from August 7–15, 2015, respectively. Canada welcomed the 40 other countries/nations of the Americas to Toronto and the municipalities of the Greater Golden Horseshoe Area in Ontario where the summer sports events of the 2015 Pan and Parapan American Games were hosted.

Environment and Climate Change Canada’s (ECCC) mission and mandate for the TO2015 Games was to provide essential services for enhanced weather monitoring and forecasting and for local-level preparedness activities. The key objectives were to enhance public safety and decision making by: issuing weather warnings; forecasting weather conditions; supporting critical weather sensitive government services; and monitoring atmospheric conditions.

The funding received by ECCC was used to provide state-of-the-art, 24/7, dedicated, venue-specific weather services during the Games (i.e., 24 hours per day, 7 days per week).

Although ECCC’s mandate for the Games was to provide venue-specific forecasts and alerts, various ongoing research and development activities were aligned to take advantage of the unique opportunities provided by the Games. ECCC’s research showcase for the Games leveraged our state-of-the-art science and technologies. The goal was two-fold: support ECCC’s operations during the Games, and learn from the research and development to make a great meteorological service even better.  

ECCC showcased a number of new technologies and instruments, which are described in the following sections. The research instrument platforms provided observations that supplemented the automated land- and marine-based Mesonet. All available observations were used to increase our understanding of meteorological and air quality science, particularly over an urban environment. ECCC will use this new scientific information to improve the accuracy and lead time of its alerts.

Automated Transportable Meteorological Observing System (ATMOS) - TO2015 Pan and Parapan American Games

Ten 10-m ATMOS surface weather stations were deployed during the 2015 Pan Am and Parapan Am Games as the foundation of the high-resolution atmospheric monitoring network, the Mesonet, built by Environment and Climate Change Canada (ECCC) in support of the Games. 

The ATMOS stations collected 1.5-m temperature and humidity, pressure, 10-m wind speed and direction, insolation, black globe temperature, precipitation, and the difference in temperature between the top and bottom of the tower (local stability). Samples were made every 5 seconds and these were used to generate 1-min averages. Data then underwent thorough quality control.

These stations were sited in a variety of environments chosen to represent the larger area around the station and included cropped fields, pasture, dirt/gravel and non-agricultural grassy areas. One ATMOS station (A6T – North York) was deployed on a flat, gravel rooftop and had a considerably shorter mast for wind measurements. Temperature difference was not recorded at this station. Exposure was typically good with obstructions 50 m or more away on all sides.

At two stations, (A3T – Claremont and A6T – North York), a WXT520 compact station was included as part of the instrumentation in order to facilitate comparisons with standard ATMOS data. The WXT520 data are not included in the Legacy Archive dataset.

Pollutant Transformation, Ground-based Pollutant Monitoring Multi Parameters - Validated Data - Fort McKay, Oil Sands Region

Long Term Air Pollutant and Meteorological Monitoring at Fort McKay’s Oski-ôtin site: Validated data

Continuous monitoring of multiple air pollutants along with meteorological conditions began in Fort McKay at the Oski-ôtin site in August 2013. The purpose of Oski-ôtin’s enhanced monitoring is to gain a clearer picture of the mixture, transport and fate of air pollutants produced from the different oil sands related activities. Compared to the pre-existing monitoring conducted by Wood Buffalo Environmental Association (WBEA) in Fort McKay and throughout the region, the Oski-ôtin site provides measurements for a larger number of pollutants using research grade instruments (configured to be more precise at lower concentrations). Instruments located at this site also monitor pollutants, winds and temperatures at multiple heights above the ground. 

The Oski-ôtin site is located 0.6 km south of the Fort McKay WBEA air monitoring site (AMS 1 Bertha Ganter); therefore, peak concentrations of sulphur dioxide (SO2), nitrogen oxides (NOx), particulate matter (PM2.5) and ozone (O3), are generally similar at both sites in time and concentration. Oski-ôtin’s enhanced monitoring capacity shows that other pollutants, including several volatile organic compounds (VOCs), carbon monoxide (CO) and particle-related chemical species (e.g., sulphate, black carbon), regularly occur in the air over Fort McKay at concentrations above regional background levels. Generally, these pollutant concentrations are not of immediate concern, but cumulative impacts in the long-term can be significant. Elevated VOC concentrations can contribute to odour events in Fort McKay.

Both preliminary data and final, validated data from the Oski-ôtin site are available. Following an extensive data quality assurance and quality control process, the final data are typically made available within twelve months of being collected. The final, validated data can support improvements to modeling capability to predict current and future air pollutant levels and surface deposition amounts near and also far downwind of the oil sands.
