Tageswerte

Tageswerte is a German term that refers to values measured or reported for each calendar day. In practice, Tageswerte denote daily observations used to describe the level or state of a quantity on a given day and are collected across a range of domains, including meteorology, finance, and health statistics.

In meteorology and climatology, Tageswerte describe daily quantities such as the Tageshöchsttemperatur (daily maximum temperature), Tagesniederschlag (total daily precipitation), and Tagesmitteltemperatur (daily mean temperature). These daily values are the building blocks of climate data records, are used to compute climate normals, and enable trend analyses and regional comparisons.

In finance, Tageswerte denote daily values of financial instruments or indices, such as the daily closing price, opening price, high and low of the trading day, and daily trading volume. Such values form time series that support market analysis, reporting, and performance measurement.

Data collection and processing for Tageswerte typically involve fixed observation times or end-of-day summaries, with attention to consistent time standards, instrument calibration, and handling of missing or anomalous data. When combining data from multiple sources, harmonization of units and time zones is important.

Limitations include the relatively coarse granularity of daily data, which may mask intraday variability. Tageswerte are most informative for identifying long-term trends, seasonal patterns, and comparative analyses rather than short-term fluctuations.
