Ontario Mosquito data

Datasets Description

Ontario Public Health Units Reference Data

Description:
This dataset provides a standardized reference list of all 34 public health units in Ontario, Canada. It serves as a lookup table to ensure consistent naming and regional categorization across associated public health datasets.

Key Variables:

  • HU: The unique abbreviation for each public health unit.
  • ID: A unique numerical identifier for each health unit.
  • PublicHealthUnit: The full, official name of the public health unit.
  • RegionName: The broader geographical region in which the health unit is located.

Data Provider: Ontario Public Health.

Provincial Weekly Mosquito Abundance by Health Unit (2002-2024)

Description:
This dataset contains weekly records of mosquito abundance across Ontario’s 34 Public Health Units from 2002 to 2024. Each entry represents the average number of mosquitoes per trap per day for a specific species (or species group) within a particular health unit during a given week. This level of aggregation enables analysis of regional mosquito population dynamics while maintaining weekly temporal resolution.

Key Variables:

  • Temporal and Geographical Identifiers:
    • YEAR, Week_Code
    • HU (Public Health Unit abbreviation)
  • Biological Data:
    • Species (Mosquito species or species group)
    • Number (Weekly average mosquitoes per trap per day for this species in this health unit)

Data Provider: Ontario Public Health.

Ontario West Nile Virus Positive Mosquito Pools by Health Unit (2002-2024)

Description:
This dataset contains weekly records of West Nile Virus (WNV) positive mosquito pools detected across Ontario’s Public Health Units. The data spans the mosquito surveillance seasons from 2002 to 2024, providing a comprehensive record of WNV activity patterns across the province. This information is crucial for tracking disease spread, identifying high-risk areas, and informing public health interventions.

Key Variables:

  • Temporal Identifiers:
    • Year, Week, YearWeek
    • StartDate, EndDate (defining the specific date range for each monitoring week)
  • Geographical Identifier:
    • HU (Public Health Unit abbreviation)
  • Primary Metric:
    • Count (Number of WNV-positive mosquito pools detected in the specified health unit during the given week)

Data Provider: Ontario Public Health.

Ontario Weather Station Metadata for Public Health Research

Description:
This dataset provides detailed location information for 193 weather stations across Ontario with long-term historical climate records. These stations serve as essential data sources for studying environmental drivers of mosquito populations and mosquito-borne disease transmission. Researchers can use this metadata to identify and select appropriate weather stations for their specific geographical and temporal study requirements.

Key Variables:

  • Geographical Information:
    • Longitude, Latitude (Geographic coordinates of each station)
    • Station_Name (Official name of the weather station)
  • Station Identifiers:
    • Climate_ID (Unique climate identifier)
    • station_ID (Unique station identifier)

Data Provider: Prepared by LAMPS using data from the Environment and Climate Change Canada Climate Data Center.

Ontario Daily Weather Station Data (2018-2023)

Description:
This dataset provides comprehensive daily weather observations from 193 stations across Ontario for the recent five-year period (2018-2023). The high-resolution temporal data supports research on mosquito ecology and mosquito-borne disease transmission by enabling detailed analysis of temperature, precipitation, and other meteorological factors that influence mosquito development and virus transmission dynamics.

Key Variables:

  • Station Identification & Location:
    • Station_Name, Station_ID, Climate_ID
    • Longitude, Latitude
  • Temporal Reference:
    • Data_Date, Year, Month, Day
  • Temperature Metrics:
    • Max_Temperature, Min_Temperature, Mean_Temperature
    • Heat_Degree_Days, Cool_Degree_Days
  • Precipitation & Snow:
    • Total_Rain, Total_Snow, Total_Precipitation
    • Snow_on_Ground
  • Wind & Gust Data:
    • Direction_Max_Gust, Speed_Max_Gust
  • Data Quality Flags:
    • Variables ending with _Flag indicate quality control markers for their corresponding measurements.

Data Provider: Prepared by LAMPS using historical climate data from the Environment and Climate Change Canada Climate Data Center.

AR6 Climate Projection Grid Mapping for Ontario Public Health Units

Description:
This dataset provides the spatial mapping between high-resolution AR6 (IPCC Sixth Assessment Report) climate projection grids and Ontario’s 34 Public Health Units. It enables researchers and policy makers to link long-term climate change scenarios (1980-2100) with public health data, facilitating studies on how future climate conditions may influence mosquito ecology and mosquito-borne disease risk across different regions of Ontario.

Key Variables:

  • Health Unit Identification:
    • PHU_Name, PHU_ID, HU
    • idHU
  • Spatial Reference & Grid Mapping:
    • Longitude, Latitude
    • idinOntario, idin250X183 (Unique identifiers for grid locations within the climate projection data)

Data Provider: Generated by LAMPS

Summary Tables of West Nile Virus Positive Pool Trends

Description:
This collection contains derived summary tables that consolidate and analyze West Nile Virus (WNV) surveillance data across multiple dimensions. These tables are designed to facilitate the analysis of long-term trends and seasonal patterns in WNV activity, supporting both epidemiological research and public health decision-making.

Key Variables:

  • Temporal and Geographical Identifiers:
    • PublicHealthUnit, Year, Week_Code
  • Analytical Metrics:
    • Variables include aggregated counts, annual totals, seasonal averages, and comparative metrics showing WNV positive pool distribution across different regions and time periods.
