Data Center Description
The Air Force Combat Climatology Center (AFCCC) provides users with air weather information for general aviation purposes. The following are standard products available from the website.
1. AEF Climatologies: Using standard ACC routes, these products show the historical probability that a mission will have an abort base with weather minimums for each leg of the deployment route.
2. Advanced Climate Modeling and Environmental Simulations (ACMES): ACMES is an AFCCC project in development that provides high-resolution climatology information for anywhere in the world, especially in regions where existing surface observational data is sparse or non-existent. Numerous regions are now available.
3. Cloud Ceiling Climatology Atlas: Displays a climatological occurrence frequency of a cloud ceiling at and below a given mean sea level height over a region/area. Images are displayed using a graduated color scheme and are available for all months. They may be displayed as a single image or looped.
4. Ceiling/Visibility Climatology Atlas: Displays a climatological percent frequency of occurrence of a ceiling with a particular visibility for a region/area. Images are displayed using a graduated color scheme. All months are available. They may be displayed as a single image or looped.
5. Lightning Climatology: Analysts can provide cloud-to-ground lightning-strike climatology for anywhere in the CONUS. Data format options include graphs and tables of monthly and diurnal variations of average lightning strikes and isopleth analyses of average strikes for each of eight regions or for the entire CONUS.
6. Potential Icing Climatology Atlas: Provides users with a climatological representation of possible icing conditions over a particular region. Images are available for every month and are broken into 11 height categories. They may be displayed as a single image or animated.
7. Rapid R-Factor Computation Tables: Users are able to compute (directly on the web page) Pressure Reduction Ratios or R-Factors using two computation tables.
8. Theater Climatic Probabilities (TCPs): TCPs are extensive graphics that show monthly climatology elements for designated areas. Staff weather officers/NCOs can use these products to brief operational planners and staffs.
9. Thunderstorm Frequency Climatology Atlas: Displays a climatological frequency occurrence of how often thunderstorms happen over a particular area/region. Data is based on the Operational Climatic Data Summary (OCDS) database and is available for all months. Images can be viewed singularly or animated.
