Regional Deterministic Precipitation Analysis (RDPA)¶

The Regional Deterministic Precipitation Analysis (RDPA) based on the Canadian Precipitation Analysis (CaPA) system is on a domain that corresponds to that of the operational regional model, i.e. the Regional Deterministic Prediction System (RDPS-LAM3D) except for areas over the Pacific Ocean where the western limit of the RDPA domain is slightly shifted eastward with respect to the regional model domain. The resolution of the RDPA analysis is identical to the resolution of the operational regional system RDPS LAM3D. The fields in the RDPA GRIB2 dataset are on a polar-stereographic (PS) grid covering North America and adjacent waters with a 10 km resolution at 60 degrees north, 2003-present. You can find additional information on the dataset here, and also here apart from the climate engine org page.

Earth Engine Snippet¶

// Read in Image Collections and get single image
var rdpa_ic = ee.ImageCollection('projects/climate-engine-pro/assets/ce-rdpa-daily')
var rdpa_i = rdpa_ic.first()

// Print single image to see bands
print(rdpa_i)

// Visualize precipitation for single image
var prec_palette = ["#ffffcc", "#c7e9b4", "#7fcdbb", "#41b6c4", "#1d91c0", "#225ea8", "#0c2c84"]
Map.addLayer(rdpa_i.select('precip'), {min: 0, max: 200, palette: prec_palette}, 'precip')
