“This dataset provides daily surface meteorological data from 1979 onward, designed for use in agricultural and agroecological studies. Known as AgERA5, it is based on hourly ECMWF ERA5 surface-level data. The acquisition and preprocessing of the original ERA5 data are complex and specialized tasks. By providing the AgERA5 dataset, users can bypass this process and directly access meaningful information for analysis and modeling. The variables provided in this dataset are tailored to meet the input requirements of most agricultural and agroecological models. The data has been aggregated into daily intervals in local time zones and corrected for more accurate topography with a spatial resolution of 0.1°. Corrections were made using grid- and variable-specific regression equations applied to the ERA5 dataset, interpolated to the 0.1° grid. These equations were trained on the high-resolution (HRES) ECMWF operational atmospheric model at a resolution of 0.1°. This adjustment ensures the data aligns with the most accurate topography, land-use patterns, and land-sea delineation of the ECMWF HRES model.”

R is a programming language widely used for statistical analysis, data mining, and visualization. Many companies have incorporated R into their products and services to leverage these capabilities. Here are some examples of companies integrating R into their products and how they use it:

Albedo refers to the reflectivity of a surface, representing the fraction of incoming light that is reflected rather than absorbed. Expressed as a value between 0 and 1, or as a percentage from 0% to 100%, albedo plays a critical role in determining how much energy from sunlight is retained or reflected by different surfaces. A surface with an albedo of 0 absorbs all incoming light, while one with an albedo of 1 (or 100%) reflects all of it.

A wind rose plot is an essential tool used to visualize the distribution of wind direction and speed at a specific location over a set period. This type of plot is commonly employed in meteorology, climatology, and various environmental and industrial applications where wind analysis is crucial.
