sarp.snowprofile 1.3.2 (2023-03-08)

• 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 (2020-07-25)

• initial release of sarp.snowprofile
