sarp.snowprofile 1.3.2

• Include weibull scaling and crust correction in computeRTA
• Enfore dependency on R 4.2 (older versions break functionality)

sarp.snowprofile 1.3.0

• Introduce a switch to compute profile summaries faster (see summary.snowprofile and summary.snowprofileSet)
• Fix bug in snowprofilePRO when soil layers where present; and: read SK38 if present
• Introduce function computeSLABrhogs to characterize cohesion of slabs (and also computeSLABrho for mean slab density)
• Adjust method to compute burial dates of layers to align more closely with human interpretation. see deriveDatetag
• Fix minor bug in findPWL: time window search ranges are now applied more transparent and meaningful
• Properly define popular generics with methods for the different classes (see e.g., ?computeRTA, ?deriveDatetag)
• plot.snowprofileSet
  • Introduce coloring of snowprofileSet plots according to stability indices with a compound color palette that allows identifying of index-specific classification thresholds (see ?plot.snowprofileSet, ?getColoursStability, ?getColoursPercentage)
  • add many new features for customizing snowprofileSet plots (e.g., emphasize specific layers, overplot timeseries with stability index, etc..)

sarp.snowprofile 1.2.0

• New functions
  • to compute structural stability threshold sums/ lemons (i.e., computeTSA, computeRTA)
  • to flexibly search for specific or generic weak layers and other layers of interest in the profiles (see, findPWL)
  • new and improved functionality in plot.snowprofile and plot.snowprofileSet
• Restructured snowprofile object classes to better cope with top-down measured manual profiles that potentially have unknown total snow heights.
  • Main change: Insert mandatory snowprofile field maxObservedDepth and precisely distinguish that from hs.
  • The existing constructors from snowprofile and snowprofileLayers are set up to auto-fill the fields if possible.
  • Highlight profiles with unknown hs in plot.snowprofile, add TopDown = "auto"
  • include strategy to handle unobserved basal layers
• Speed up several bottlenecks that slowed down long computations

sarp.snowprofile 1.1.0

• v1.1.0 contains a variety of minor improvements listed below. The version should be free of major bugs, but several improvements are to be done in future versions.

• Improvements of snowprofileCaaml:

  • Make routine compatible with caaml files from snowpilot.org (fix bugs related to bottom up profiles and workaround namespace issue)
  • Originally compatible with caaml files from niviz.org
  • Convert undefined grain types

• Handle grain types that are undefined in package with validate_snowprofile and reformat_snowprofile

• Enable plotting of a temperature profile that is independent of the snow layer grid

• writeSmet routine for exporting smet files

• Add object classes for snowprofileTests and snowprofileInstabilitySigns

• Add new read routine for advanced csv files containing a comprehensive set of profile information, see ?snowprofileCsv_advanced.

• Add few new field names to layer structure.

• A deriveDatetag function calculates bdates and datetags for snowprofile layers.

• A simplifyGtypes function trims unsupported IACS gtype subclasses into their supported main classes (e.g., PPsd –> PP)

sarp.snowprofile 1.0.0

• initial release of sarp.snowprofile

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
