Requirement #683 


For variable: Precipitation type at the surface

In application: High Res NWP

Goal Breakthrough Threshold
Stability/decade (if applicable)
Horizontal Resolution 0.25 km 1.5 km 5 km
Vertical Resolution 0.1 0.2 0.4
Observing Cycle 15 min 60 min 3 h
Timeliness 15 min 30 min 2 h


Validated: 7/29/11 Source: T Montmerle
Comment: - Accuracy difficult to quantify - Resolutions in km - should be a 3D variable, considering that precipitation types can be determined by polarimetric radars Confidence: tentative
Def: :Positive impact expected but not yet validated due to lack of suitable data and/or models
  • Domain: Atmosphere
