On 2003.03.12 I surfed the web for more weather information that might be used as input to the VLA Dynamic Scheduler.

Weather Discussions

"Good" weather parameters - Claire Chandler, 2003.04.01

From the Forecasts:

• 2 m height above ground temperature
• 2 m height above ground humidity

( from these we know about ice or snow )

• Precipitable Water Vapor
• Wind
• "Lifted Index" (convection) (going down, it'g going to rain...)

Rick Perley discussion, 2003.04.03

WEATHER DATA

• antenna annemometers are NOT calibrated; threshold of believability-talk to bob broilo
• phase stability rms vs. Baseline length

WEATHER MODELS

• which model to use? -- Ask the NwsMeterologists
