Real-time weather forecasting for transportation systems

A weather forecasting method for producing a weather phenomenon inference comprising:

• collecting data including at least one of (a signal attenuation-based data, (b) weather data, and (c) high frequency data indicative of environmental conditions;
• calculating weather data based on the received data, and storing in at least one database the calculated weather data as first provided weather data,
• calculating one or more time series based on the collected and/or calculated data,
• inferring a weather phenomenon based on the collected and/or calculated data to create a weather phenomenon inference, and
• storing data representing the one or more time series and/or the inferred weather phenomenon in a database in association with a cadence.

A method for inferring the presence of a weather phenomenon comprising:

• collecting microwave link attenuation data corresponding to a particular geographic location and a particular time;
• inferring the presence of a weather phenomenon at the particular geographic location at the particular time based in part on the collected microwave link attenuation data;
• accessing at least one past weather parameter value corresponding to the particular geographic location;
• and
• one of confirming and refuting the presence of the weather phenomenon at the particular geographic location and at the particular time based on the at least one past weather parameter value corresponding to the particular geographic location.
