High resolution solar irradiance variability climatology dataset part 2: classifications, supplementary data, and statistics

Dataset description

High resolution surface solar irradiance series classification, cloud shadow and enhancement statistics, and satellite observations for studying intra-day surface solar irradiance variability.

Part 2 of 2

This dataset is the derived from the 1 Hz observational record of direct, diffuse, and global horizontal irradiance measured by the Baseline Surface Radiation Network station at Cabauw, the Netherlands. More information about the observational site Cabauw can be found at the Ruisdael Observatory website.

Methodology

Processing of data and its usage described in a manuscript ready for submission. Pre-print will be added as soon as it is available. Processing scripts will be published with GitHub-Zenodo, and added here as well.

Dataset contents

This dataset contains daily time series with the following data, from 2011-02 until 2020-12-31:

1. Cloud shadow and cloud enhancement time series classifications (see methodology)
2. CAMS McClear for clear-sky global horizontal irradiance (version 3.1)
3. CAMS McClear input (aerosols, ozone, and total column water vapour)
4. Solar elevation and azimuth angles (calculated using PySolar)
5. Quality flags (non-official and optimized for 1-Hz, refer to BSRN at PANGAEA for official 1-minute quality flags)
6. Cabauw observatory tower wind speed and direction

Additional satellite data time series from 2014-01 until 2016-12:

1. MSGCPP satellite data for an area over central Netherlands (CLAAS2 source)
2. Post processed timeseries of cloud types over Cabauw derived from this MSGCPP satellite data

Statistics files:

1. cloud shadow and cloud enhancement event detection and event statistics based on the time series
2. daily radiation statistics

And finally, for all days there are quicklooks available that visualize the irradiance time series, classification, and if available satellite data.
