An open source library for common hydrological and meteorological issues

An open source library for common hydrological and meteorological issues.

The motivation for implementing this library grows out of my personal and academic projects where I face some typical problems repeatedly.

functionalities

The library contains following functionalities, which are updated regularly.

EDA

1. estimates of location: arithmetic_mean, weighted_arithmetic_mean, trimmed_mean,geometric_mean,exponential_mean,harmonic_mean,median,weighted_median,percentile
2. estimate_of_variability: mu, avg_absolute_deviation_from_mean, avg_absolute_deviation_from_median, median_absolute_deviaton,variance, stdev, range, iqr
3. estimates of distribution: coefficient_of_skewness, coefficient_of_kurtosis TODO #7, mode
4. quality investigation: missing_days, duplicates, outlier

TimeSeries

• subset_timeframe: subdivide time series based on a timeframe
• subset_period: subdivide time series based on a period
• hyd_year: derive the hydrological year based on a given start day and month
• principal_values: derive principal values (HHX, HX, MHX, MX, MNX, NX, NNX) from a time series
