Due to the curvature of the Earth, the height of a radar beam, in relation to the ground, increases as it travels further from the radar. When the radar is pointed down near the ground (a low elevation angle), the beam starts off near the ground but then its height above the ground slowly...

DPQPE product: DPQPE stands for: Dual Polarization Quantitative Precipitation Estimation. The DPQPE product is available only for S-Band radars. It is a two-dimensional representation of the precipitation rate estimated by the lowest sweep of the radar (elevation angle of 0.4 degrees for the...

This product shows the rain accumulation, in mm, over the last 24 hour period based on PRECIP-ET and DPQPE. For PRECIP-ET, this product is available every 10 minutes for C-Band radars and every 6 minutes for S-Band radars. For DPQPE, this product is available every 6 minutes.

The PRECIP-ET (PRECIPET on images) is an extension of the PRECIP product (hence the use of ET in the product name). Compared to the previous PRECIP product, the PRECIP-ET performs a suite of additional quality control (QC) tests and tracks issues better. For example, Doppler filters might be...

Atmospheric concentrations and deposition rates of particulate elements are important indicators for determining the potential impacts of the oil sands industries on the local environment. The datasets consist of measured ambient air concentrations (in PM2.5 and PM2.5-10) and estimated deposition...

Precipitation measurements in the Environment and Climate Change Canada (ECCC) surface network are a necessary component for monitoring weather and climate and are required for flood and water resource forecasting, numerical weather prediction and many other applications that impact the health...
