The Air Quality Health Index (AQHI) is a scale designed to help quantify the quality of the air in a certain region on a scale from 1 to 10. When the amount of air pollution is very high, the number is reported as 10+. It also includes a category that describes the health risk associated with the...

Daily climate observations are derived from two sources of data. The first are Daily Climate Stations producing one or two observations per day of temperature, precipitation. The second are hourly stations that typically produce more weather elements e.g. wind or snow on ground. Only a subset of...

Real-time water level and flow (discharge) data collected at over 2100 hydrometric stations across Canada (last 30 days).

A cross-country summary of the averages and extremes for the month, including precipitation totals, max-min temperatures, and degree days. This data is available from stations that produce daily data.

Canadian hourly climate data are available for public access from the ECCC/MSC's National Climate Archive. These are surface weather stations that produce hourly meteorological observations, taken each hour of the day. Only a subset of the total stations found on Environment and Climate Change...

A series of surface climate parameters have been measured by members of the Climate Processes Section at the Borden Forest Research Station (44°19’N, 79°56’W) beginning in January 2006. The initial data included precipitation. In 2007, carbon dioxide fluxes from the soil (soil respiration) began...

This dataset contains the ambient dissolved concentrations of organophosphate esters (OPEs) and polybrominated diphenyl ethers (PBDEs) in North Atlantic Ocean (Greenland Sea) as well as a summary of the passive polyethylene samplers (PEs) deployed. Organophosphate esters (OPEs) have been found in...

Temporal trends and climate related parameters affecting the fate of legacy persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) were examined in landlocked Arctic char from four lakes in the Canadian Arctic. Among biological...
