Terminal Aerodrome Forecasts (TAF)

• Operational forecasts of aviation weather conditions at an aerodrome

• National Weather Service (NWS) issues TAFs at least 4 times daily for ~700 locations

• Text code form• Evolving WXXM

form

Model Output Statistics (MOS)• Successful,

operational forecast technique

• Accurate, reliable guidance

• Ceiling, visibility, and many other weather elements

• Four times daily

Model Grids

Least Squares

Regression

Sensible Weather Elements

Localized Aviation MOS Program (LAMP)

• Update to MOS

• Focus on aviation weather elements

• Issued hourly

Delivering LAMP

• Today– Text bulletins– Guidance TAFs in text– BUFR, GRIB

• NextGen– Grids via Web Coverage Service (WCS)– Guidance TAFs in WXXM– Probabilistic TAFs in WXXM

“Probabilistic TAFs” in WXXM

• Not just ceiling• Conditional ceiling (conditioned on

precipitation occurring)• Visibility• Conditional visibility (conditioned on

precipitation occurring)• Chance of freezing/frozen precipitation

Collaborating to Deliver Web Services

• NOAA will have many data sources• No need for Cube Edge Input Servers (CEIS) at

every data source• MDL will implement a set of Source Service

Adapters (SSA) and transfer WXXM documents to CEIS at NOAA’s Earth System Research Laboratory (ESRL)
