Verif - Version 1.4.0

This version actively uses ensemble members from the input files.

New metrics and diagrams

• -m fcrps computes the fair continuous ranked probability score from an ensemble
• -m rankhist shows a rank histogram
• -m spreadskillratio computes the ratio of ensemble standard deviation to the root mean squared error of the ensemble mean
• -m obsstddev computes the standard deviation of observations
• -m fcststddev computes the standard deviation of forecasts

Updated metrics and diagrams

• -m spreadskill now uses the ensemble standard deviation as spread (instead of the spread between two quantiles)
• -m spread now uses the ensemble standard deviation as spread (instead of the spread between two quantiles)
• -m timeseries now also shows ensemble members
• -m obsfcst now supports ``-type map`

New data manipulation options

• -Tagg accepts change and abschange
• -fcst accepts ensemble:mean, ensemble:variance, and ensemble:<number> (where number is an ensemble member index)

Input files can now have a time axis with units other than seconds since 1970-01-01.

Verif - Version 1.1.0

New features

• Support for reading OpenDAP files, meaning that verif can read files directly from a remote server supporting OpenDAP (for example thredds <https://www.unidata.ucar.edu/software/thredds/current/tds/>_).
• Read arbitrary fields (such as pre-computed CRPS) from file
• Added axes: -x leadtimeday, -x timeofday, -x dayofyear, -x monthofyear, -x dayofmonth, -x day
• Added -a to annotate graphs (put text next to each data point)
• Added -x obs and -x fcst to plot scores as a function of observed or forecasted value
• Allow subsetting of forecasts initialized at certain times of the day (-tod)
• Added -type rank, -type impact, and -type mapimpact
• Added -obsrange to subset based on observed values
• Accept vector input for -ms and -lw
• Added python 3.7 support (thanks to @tommz9 <https://github.com/tommz9>_)

Changes to command-line options

• -ls no longer accepts marker specification, e.g. o-. Markers must be specified separately using -ma (e.g. -ls - -ma o).

New metrics/diagrams

• -m bssrel Brier skill score, reliability component
• -m bssres Brier skill score, resolution component
• -m autocorr to show autocorrelation of error in space or time
• -m diff to show difference in aggregated statistics
• -m fss to show fractions skill score
• -m pithistslope to show slope of the pit histogram
• -m pithistshape to show the shape of the pit histogram (e.g. U-shape)
• -m ratio to show ratio of aggregated statistics

Changes to metrics

• Renamed -m pitdev to -m pithistdev
