WaterSip

WaterSip is a diagnostic software tool that identifies source, transport and arrival properties of atmospheric water vapour. It implements the moisture source diagnostic of Sodemann et al. (2008) for input data from either FLEXPART particle output or Lagranto trajectories.

Input file options

The WaterSip input file is a text file with options that are specified for different option groups. Option groups are identified by square brackets (e.g. [Case]). There are 7 option groups which can appear in random order in the input file:

• Case: general settings related to the case to be extracted
• Grids: specification of different output grids
• Diagnostrics: parameters of the moisture diagnostic
• Output: general output settings
• Variables: selection of output variables
• Flexpart: options specific to runs using FLEXPART particle output
• Lagranto: options specific to runs using Lagranto trajectories
