This text presents the meteorological data at daily frequency collected at Lysimeter 10 located at the National Green Infrastructure Facility.

=============================
!!! Version update - v2.0 !!!
=============================
03.07.2020 - Changes to v1.0
* Minimum value of relative humidity on 21.11.2019 was reported falsely as 0 %. The corrected value is 63.0 %.
* Data from 20.04.2020 and 21.04.2020 have been added to complete a 365-day cycle.
* Mean wind direction data have been added. Calculations were done according to Grange (2014).

==================================================================
Explain the relationship between multiple data sets, if required:
==================================================================
All the data are collected from the same setup using a weather station, rainfall gauge and a net radiometer.

=====================================
Key words used to describe the data:
=====================================

Lysimeter, SuDS, Green Infrastructure, Air Temperature, Relative Humidity, Barometric Pressure, Wind Speed, Net Radiation, Rainfall


==========================

Date(s) of data collection: 
============================

22.04.2019 - 19.04.2020 in v1.0
22.04.2019 - 22.04.2020 in v2.0

============================
Geographic coverage of data:
============================
Newcastle upon Tyne, UK
Location of the lysimeter: 54.973865, -1.625792

================================================================
Data validation (how was the data checked, proofed and cleaned):
================================================================
Data was collected at every 10 s interval. Mean, minimum and maximum values were calculated using all the raw data.
