The above loop uses radar and visible/IR satellite data obtained from Aviation Weather Center (AWC), lightning (GLM) data from NOAA nowCOAST, and observations (for flight category and weather) from MesoWest. The radar, lightning, visible satellite, IR satellite, SIGMETs/CWAs, and flight categories/weather can be toggled on/off. When both the flight category and weather are displayed, the flight category icon will be on the inside and the partially-transparent weather color on the outside. Clicking on the map will start/stop the loop. Left-clicking on the "Speed" area will slow the loop and right-clicking will accelerate the loop, ranging from 0.05 to 5 second interval. To toggle the lower-left menu visible/hidden, click the ≪ or ≫ button. Additional URL parameters include lt (center latitude), ln (center longitude), zm (zoom level, 0-12), nolabel (removes flight category icon ID labels), hidemenu (hides the menu options on the lower left), wide (thicken US state boundaries), county (include US counties and other political boundaries based on zoom level), hidefir (hide FIR boundary), zseareas (add the ZSE ARTCC areas), and start (UTC start date/time, YYYYMMDDhhmm format, AWC data goes back up to 2 days, GLM data up to 5 hours). The URL should auto-update with the current settings, allowing for an easy bookmark/favorite. The NWS Radar page and NWS Satellite page also are available.
