Abstract:
Die meteorologischen Daten zu den Temperatur-, Feuchte- und Windfeldern wurden während vier Messkampagnen in Stuttgart im Sommer 2017, Winter 2017, Sommer 2018 und Winter 2018 erhoben. Doppler Lidarsysteme und ein Mikrowellenradiometer wurden zur Erfassung und zur Analyse der horizontalen Struktur des innerstädtischen Windfeldes und der vertikalen Struktur der urbanen Grenzschicht eingesetzt. Die Messungen wurden im Rahmen des Verbundprojekts „Dreidimensionale Observierung atmosphärischer Prozesse in Städten (3DO)“ durchgeführt. 3DO gehört zu einem der drei Module der BMBF-Fördermaßnahme Stadtklima im Wandel (UC2).
Mehr Information über Ziele der UC2 Fördermaßnahme ist auf http://www.uc2-program.org/ und in den aufgelisteten Übersichtspublikationen zu finden.

Abstract (englisch):
This dataset of meteorological observations (temperature, humidity, wind) was collected during four field campaigns in Stuttgart, Germany, in summer 2017, winter 2017, summer 2018, and winter 2018. Doppler lidars and a microwave radiometer were deployed to investigate horizontal structures of intra-urban horizontal wind field patterns and vertical structures of the urban boundary layer. The measurements were conducted within the project ‘Three-dimensional Observation of Atmospheric Processes in Cities’ (3DO). 3DO is one of three modules of the programme ‘Urban Climate Under Change’, [UC]2, funded by the German Federal Ministry of Education and Research (BMBF).
More information on the goals of the UC]2 programme can be found on http://www.uc2-program.org/ and in the overview papers listed below.

DATA SET DESCRIPTION

1. Spatial coverage

The measuring data were collected during intensive observation periods (IOP) in Stuttgart, Germany, under the BMBF Programme ‘Urban Climate Under Change’ [UC]2.

2. Temporal coverage

01.02.2017 - 31.08.2018

3. Data file structure and variables

The parent UC2_IMK_TRO_KIT data folder contains archived directories, corresponding to a particular measuring device (WINDCUBE8, RPG_HATPRO_G4 and VIRTUAL_TOWERS ).
WINDCUBE8 folder contains files of wind vectors measurements at different heights retrieved from Windlidar WINDCUBE8.

RPG_HATPRO_G4 folder contains data files from microwave radiometer measurements. The stored variables are cloud liquid water content, atmosphere mass content of water vapor, infrared radiometer brightness temperature, air pressure, as well as vertical temperature profiles and vertical absolute humidity profiles.

VIRTUAL_TOWERS folder contains profiles of horizontal wind retrieved with the dual-Doppler Lidar technique ‘Virtual towers’.

4. Devices and Locations

The Doppler wind lidar WINDCUBE8 (WLS8-3 manufactured by Leosphere) was located on a rooftop of the city hall in the city centre (48.774667°N / 9.178287°E). The name of this location is cityhall. This abbreviation is the part of file name; see paragraph 6.

The microwave radiometer (RPG HATPRO G4) manufactured by RPG-Radiometer Physics GmbH was located on a rooftop of the city hall tower in the city centre (48.775017°N / 9.177928°E). The name of this location is cityhalltow. This abbreviation is the part of file name; see paragraph 6.

The six virtual towers were located in the Stuttgart city basin and in the Neckar valley. The names and coordinates of the six virtual towers are: wolfram (48.792912°N / 9.180950°E), citycannstat (48.788833°N / 9.190096°E), citywera (48.787575°N / 9.194673°E), naehter (48.780160°N / 9.226197°E), bcmercedes (48.787883°N / 9.233923°E), uthbherzogen (48.794566°N / 9.245064°E). These abbreviations are the parts of file names; see paragraph 6.

5. Type of files

WINDCUBE8, RPG_HATPRO_G4, VIRTUAL_TOWERS folders contain NetCDF-files created using Matlab R2016b regarding CF-1.7 convention.

6. The file name

The name of the NetCDF-file consists of some abbreviations:
campaign-location-site-acronym-data_content-origin_date-version.nc

Example: IOP02-S-cityhall-KITimktro-meteo-20170815-1.nc

campaign: IOP0X , where X is the number of an IOP. X=1: February-March 2017. X=2: June-August 2018. X=3: January-March 2018. X=4: June-August 2018.

location: S indicates Stuttgart.

site: i.e cityhall stands for location of WINDCUBE8. See paragraph 4.

acronym: KITimktro, stands for Karlsruhe Institute of Technology, Institute of Meteorology and Climate Research, Department Troposphere Research.

origin_date: measuring date in the format YYYYMMDD (year, month, day) YYYYMMDD.

version: 1

data_content: see paragraph 7.

7. Data content

WINDCUBE8 folder contains data files with two different data contents: meteo and w. The data file with the content meteo includes time series profiles of eastward (ua) wind and northward wind (va) vectors averaged over 10 minutes periods. The data file with the content w includes time series profile of vertical wind velocity (time resolution of 7 sec).
RPG_HATPRO_G4 folder contains data files with three different data types: meteo, ta, haa. meteo includes time series of atmosphere cloud liquid water content (lwp), atmosphere mass content of water vapor (prw), infrared radiometer brightness temperature (tb), and air pressure (plev) from microwave radiometer measurement (time resolution of 4 sec). ta includes vertical temperature profiles (time resolution of 15 min) and haa contains vertical absolute humidity profiles (time resolution of 4 sec).
VIRTUAL_TOWERS includes time series profiles of eastward (ua) wind and northward wind (va) vectors (time resolution of ca. 15 min).

Information about processing of variables is given in the global attributes and in the attributes for the individual variables in each NetCDF-file.
