Within the history screen, we have the “Annual Comparison” sub-screen, where we can compare historical data for up to 4 years. The data available for comparison includes temperature (2m), solar radiation, and precipitation. The annual comparison screen is shown in Figure 4.2A below.
Figure 4.2A – Annual Comparison Screen
When entering the “Annual Comparison” screen, follow these steps:
- Select the Start Date (Nº1): Choose the starting date for your comparison.
- Select the Number of Days (Nº2): Choose the duration for the data comparison.
- Select the Distribution (Nº3):
- Normal Distribution: This shows the normal variation of data day-to-day.
- Accumulated Distribution: Data accumulates day-to-day until the end of the selected period. For example, if it rained 10mm on Day 1, 4mm on Day 3, and 15mm on Day 8, all these precipitation values will accumulate over the evaluation period.
- Resolution (Nº4):
- High Resolution: Considers data from the year 2014 onwards.
- Low Resolution: Considers data from the year 1985 onwards.
- Select the Month (Nº5): Define which month you are focusing on in your analysis.
- Select the Year(s) (Nº6): Choose up to three years to compare.
- Select Variables (Nº7): Choose from three variables:
- Temperature (2m)
- Solar Radiation
- Precipitation
After selecting all the required fields, a graph will be generated.

When selecting the accumulated data distribution, the graph will be presented as shown in Figure 4.2C below:
