&lt;div&gt;{{Campaign&lt;br /&gt;
|title=TROLIX-19&lt;br /&gt;
|description=A Sentinel-5p/TROPOMI validation campaign was held in the Netherlands based at the Cabauw Experimental Site for Atmospheric Research during September/October 2019. The 2019 TROpomi vaLIdation eXperiment (TROLIX’19) consisted of active and passive remote sensing platforms in conjunction with several balloon-borne, airborne and surface chemical measurements.&lt;br /&gt;
&lt;br /&gt;
The goal of this geophysical validation campaign was to make intensive observations for thevalidation of TROPOMI L2 main data products (such as NO2, O3, HCHO, aerosol layer height, clouds and UVAI) under realistic, non-idealized conditions with varying cloud cover and a wide range of atmospheric conditions.&lt;br /&gt;
&lt;br /&gt;
Since TROPOMI is a hyperspectral imager with a very high spatial resolution of 3.5 km x 7 km, understanding local effects such as inhomogeneous sources of pollution, sub-pixel clouds and variations in ground albedo is important to interpret TROPOMI results. Therefore, the campaign includes sub-pixel resolution local networks of sensors, involving Pandora and MAX-DOAS instruments, around Cabauw (51.97°N, 4.93°E) and within the city of Rotterdam (51.92°N, 4.48°E). Cabauw is considered rural while Rotterdam is densely populated and industrialized. CESAR (Cabauw Experimental Site for Atmospheric Research), using its comprehensive in-situ and remote sensing observation program in and around the 213 m meteorological tower (see Section 3), was the main site of the campaign with focus on vertical profiling using lidar instruments for aerosols, clouds, water vapor, tropospheric and stratospheric ozone, as well as balloon-borne sensors for NO2. The ozonesonde profiles were measured at KNMI in De Bilt which is approximately 23 km from the CESAR site.&lt;br /&gt;
&lt;br /&gt;
Instruments that were used:&lt;br /&gt;
&lt;br /&gt;
- Stationary MAX-DOAS and Pandora instruments in different locations&lt;br /&gt;
&lt;br /&gt;
- BIRA Mobile-DOAS instrument&lt;br /&gt;
&lt;br /&gt;
- NO2 sondes&lt;br /&gt;
&lt;br /&gt;
- Ozonesondes&lt;br /&gt;
&lt;br /&gt;
- NASA LIDAR ozone observations&lt;br /&gt;
&lt;br /&gt;
- Raman LIDAR CAELI&lt;br /&gt;
&lt;br /&gt;
- In-situ NO, NO2, O3 and aerosols measurements&lt;br /&gt;

&lt;div&gt;{{Campaign&lt;br /&gt;
|title=CINDI-3&lt;br /&gt;
|description=Third Cabauw Intercomparison of Nitrogen Dioxide measuring Instruments, which took place at the Cabauw Experimental Site for Atmospheric Research (CESAR) from 21 May until 24 June 2024. CESAR is one of the main facilities of the Dutch Ruisdael Observatory located midway in between the cities of Rotterdam and Utrecht, and managed by KNMI.&lt;br /&gt;
&lt;br /&gt;
Over 100 researchers from 18 countries participated in CINDI-3, operating 32 UV-Vis DOAS instruments to compare and intercalibrate measurements of air pollutants and to support the validation of satellite measurements from space-borne instruments such as Sentinel-5p/TROPOMI. CINDI-3 is the third intercomparison campaign of this kind. The overall campaign planning and coordination was carried out by a steering committee, led by BIRA-IASB (Royal Belgian Institute for Space Aeronomy), coordinating the CINDI-3 intercomparison schedule and all additional activities such as the mobile and aircraft observations.&lt;br /&gt;
&lt;br /&gt;
The main science objectives of CINDI-3 are the following:&lt;br /&gt;
&lt;br /&gt;
-  To assess the consistency of slant column measurements of several key target species (NO2, ozone, O4 and HCHO) of relevance for the validation of S5P and the future ESA atmospheric&lt;br /&gt;
Sentinels, through coordinated operation of a large number of DOAS and MAXDOAS instruments from all over the world.&lt;br /&gt;
&lt;br /&gt;
- To study the relationship between remote-sensing column- and profile-measurements of NO2, HCHO and ozone and reference in-situ concentration measurements of the same species.&lt;br /&gt;
- To investigate the horizontal representativeness of MAXDOAS measuring systems in view of their use for the validation of satellite tropospheric measurements featuring ground pixel areas in the range of 25-50 km2.&lt;br /&gt;
&lt;br /&gt;
CINDI-3 was organized as part of the ACTRIS-CREGARS Topical Center for trace gas remote sensing, within the framework of the collaboration between ACTRIS and NDACC, and conducted with additional support from ESA, NASA and from the EU Horizon2020 ATMO-ACCESS project (https://www.atmo-access.eu/).&lt;br /&gt;
Additionally, the campaign was supported by KNMI.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
- Static MAXDOAS and zenith-sky DOAS instruments&lt;br /&gt;
&lt;br /&gt;
- In situ ICAD instrument&lt;br /&gt;

- Brewer&lt;br /&gt;
&lt;br /&gt;
- Ozone sondes&lt;br /&gt;
&lt;br /&gt;

|title=CINDI-3&lt;br /&gt;
|description=Third Cabauw Intercomparison of Nitrogen Dioxide measuring Instruments, which took place at the Cabauw Experimental Site for Atmospheric Research (CESAR) from 21 May until 24 June 2024. CESAR is one of the main facilities of the Dutch Ruisdael Observatory located midway in between the cities of Rotterdam and Utrecht, and managed by KNMI.&lt;br /&gt;
&lt;br /&gt;
Over 100 researchers from 18 countries participated in CINDI-3, operating 32 UV-Vis DOAS instruments to compare and intercalibrate measurements of air pollutants and to support the validation of satellite measurements from space-borne instruments such as Sentinel-5p/TROPOMI. CINDI-3 is the third intercomparison campaign of this kind. The overall campaign planning and coordination was carried out by a steering committee, led by BIRA-IASB (Royal Belgian Institute for Space Aeronomy), coordinating the CINDI-3 intercomparison schedule and all additional activities such as the mobile and aircraft observations.&lt;br /&gt;
&lt;br /&gt;
The main science objectives of CINDI-3 are the following:&lt;br /&gt;
-  To assess the consistency of slant column measurements of several key target species (NO2, ozone, O4 and HCHO) of relevance for the validation of S5P and the future ESA atmospheric&lt;br /&gt;
Sentinels, through coordinated operation of a large number of DOAS and MAXDOAS instruments from all over the world.&lt;br /&gt;
- To study the relationship between remote-sensing column- and profile-measurements of NO2, HCHO and ozone and reference in-situ concentration measurements of the same species.&lt;br /&gt;
- To investigate the horizontal representativeness of MAXDOAS measuring systems in view of their use for the validation of satellite tropospheric measurements featuring ground pixel areas in the range of 25-50 km2.&lt;br /&gt;
&lt;br /&gt;
CINDI-3 was organized as part of the ACTRIS-CREGARS Topical Center for trace gas remote sensing, within the framework of the collaboration between ACTRIS and NDACC, and conducted with additional support from ESA, NASA and from the EU Horizon2020 ATMO-ACCESS project (https://www.atmo-access.eu/).&lt;br /&gt;
Additionally, the campaign was supported by KNMI.&lt;br /&gt;

|title=KNMI Clouds - cloud cover retrieved from infrared measurements at 10 minute intervals at CESAR observatory&lt;br /&gt;
|description=Four cloud cover parameters are retrieved continuously from sky temperature measurements by a scanning infrared radiometer (NubiScope). These parameters are resp. total, low -, middle - and high level cloud cover. Only measurements 20 degrees above horizon are used to create a hemispherical cloud mask. The temperature deviation of a sky pixel from an estimated background sky temperature determines whether a pixel is considered to be cloudy or clear sky.
