Time Series


Time series of nearly all products can be visualized for diagnosis of algorithm and gauge performance. For example, a time series can show how precipitation estimates are derived from basic variables. A time series can be created at a gauge location or a lat-lon point.

Following are examples how to diagnose PPS and DP performance at a gauge location. The first plot shows hourly accumulations and the second shows PPS and DP rates that resulted in the accumulations. For more information of the different rainrates and relationships to HHC see: Rainfall Rate Relationships. More info on the different products and tabs is provided below.

TIP: If you enter numbers for a specific latitude and longitude, do not move your mouse into the image below or your selected area will change.


HADS gauge MRIT2 is selected along with hourly accumulations for PPS and DP. Data scales can be changed with the "Plot" tab.


PPS and DP rates are shown and can be realted to the Hybrid Hydrometeor Classification classes. DP variables for the four lowest tilts can be plotted.



In Time Series, there is no available method for zooming in on just a portion of the map. You will see an image similar to Figure 1. If you would like to select a specific area under the Point tab, you must do the following.

  1. Go to the QPE tab and select a region, as shown in Figure 2.
  2. When you return to the Time Series tab, the previously selected area will now be in your Plot Point Selection map, as shown in Figure 3.

The Plot tab allows you to adjust your scale so that your Time Series will plot within the provided graph. You also have the option of outputing the data to a text file.
