The indicator E8 measures COVID-19 lockdown effects on output inventory level at finished goods production sites. To contain COVID-19 pandemic, EU Member States have taken a restricitve measures. According to EUROSTAT, these imposed measures had in general a negative effect on demand and thus on industrial production in many areas.At the logistic areas operated at the production sites such as motor vehicle manufacturing, the large number of metal objects (e.g. machinery, vehicles) produces a strong signature in the radar backscatter signal. The observations provided by the Synthetic Aperture Radar satellites such as the C-band Copernicus Sentinel-1 or the X-band Iceye satellites permit comparative measurements between 2019 and 2020 of the average backscatter signal at the output logistic areas.The output of the indicator E8 algorithm is a CSV file containing statistics of Sentinel-1 backscatter signal for selected aoi and time period.To generate the indicator E8 data, navigate to EDC Browser, select the required input parameters and follow the check-out wizard to complete your order. Produced data will be uploaded directly into your JupyterLab environment on EDC.

| default_B0_stDev | The standard deviation of data values is a statistical measure that indicates the amount of variation or dispersion of the data values. |
| default_B0_sampleCount | The sample count parameter specifies the number of samples to include in the statistical calculation. |
| default_B0_noDataCount | The noDataCount parameter is the number of data values that are considered "no data" or "missing" in the specified aoi and time period. |
Prices are defined based on the selected AOI and time range. The processing price for 1 km^2 is 9 EDC credits per year of input data. Regardless of the size and time period, the minimal cost for initiating a request is 20 EDC credits.
