history+ with new analysis tool for seasonal accumulations

Historic data now aggregated - We introduced a powerful new tool in our history+ interface: accumulations. This tool combines past years with seasonal forecast data, providing a comprehensive view to investigate upcoming seasons (e.g. GDD analysis).

The new accumulation tool was added to our history+ subscription and can be used by all subscribers.

The analysis is available for the following weather variables:

  • Growing Degree Days (GDD): Agronomists mostly use this variable to predict crop developments and define current and future crop growth stages, usually over one season.
  • Precipitation: Analyse total precipitation sums over a defined time period.
  • Evapotranspiration: It describes the sum of evaporation (soils, lakes, seas) and transpiration (plants) that can now be aggregated for a season.

Using the accumulation analysis tool is straightforward. Define the season’s start date and duration in days. The x-axis defines the days after the defined season start, and the y-axis shows the accumulation of the selected weather variable.

The blue line shows the past accumulation for the past days of the season. This data is available from the meteoblue high-resolution NEMS weather model (spatial resolution between 4 and 30km) or the ERA5 re-analysis model (30km resolution). The purple line shows the forecast data for the next 7 days, which can also be accessed through our Meteogram Agro. Next, different statistical analyses of meteoblue NEMS or ERA5 are shown as percentiles (light pink lines). These lines are based on 30 years of historical data. In more detail, „pm10“ represents the third-coldest year out of 30 years, "p50" an average year, „and p90" the third-hottest year. The pink lines visualise seasonal forecast data provided by various national weather services to give a wide overview for up to 6 months into the future. The bolt pink lines show an ENSEMBLE forecast, which is a mean based on over 300 individual forecasts from different forecast centres and is more likely to be true than any single model.

Besides the new tool, history+ also provides a huge range of unique features, some of which are also mainly developed for agricultural use cases, such as:

  • Crop Risk Analysis to check the risk for drought, heat, or frost for a selected crop or to monitor and evaluate crop risks based on the current season weather, the 7-day and the seasonal forecast.
  • Risk Assessments analyze past weather data, which is explained in a video

You can test history+ free of charge for Basel to learn more about the different features.
