New forecast tools
Extended Cloud Forecast
This new feature extends the 48 hour forecast by an additional 8 days! The extended cloud forecast is based on of the Global Forecast System (GFS) forecast and is updated twice a day.
The extended forecast will load automatically below the 48 hour CMC forecast. Each forecast block in the extended forecast represents 3 hours and is color calibrated to the same scale as the detailed 48 hour forecast.

Aerosol Optical Depth updates (still experimental)
Aerosol Optical Depth (AOD) has been a popular map layer since its release a few weeks ago. This update adds two new light wavelengths (440nm and 660nm) to aid in astrophotography planning.
|
0 to 0.1 Clear |
0.1 to 0.2 Average |
0.2 to 0.3 Above average |
0.3 to 0.4 Some haze |
0.4 to 1 Hazy |
1 to 2 Very hazy |
> 2 Extremely hazy |
Wavelengths are reduced by atmospheric pollutants at different rates. Short wavelengths like blue (~440nm) is generally the first to be reduced by pollutants such as smoke, but longer wavelengths like red can still make it through (~660nm). Sometimes a hazy night might still be good for collecting Hydrogen alpha data for your image :)
Enjoy and keep the great feedback coming!
