RADAR-2 - Getting issue details... STATUS

DevOps

Repo: https://github.com/obrienlabs/radar

Architecture

There are several data sites that serve up doppler radar images every 6-10 minutes.  In addition we have correlating satellite, lightning and weather data.  We also have historical radar imaging for missed downloads.

Analysis

Data Model

There are several radar sites across canada that provide individual and combined images at 10 and 6 minute intervals.

Image Format

480 x 560 with legend - active area is 480 x 480

Intermittent Effects

xam is a good example

Out of order image ordering (historical)


Transient blocking from wind farms

Transient blocking from RF interference

Permanent false positive elements

single frame noise

Image gitter at 1 pixel

Noise past circular range rings

Historical radar missing data due to grid/names overlay


API
