How to use this data with a command-line HTTP-client

The data on this is meant to be downloaded by a script, while using machine-to-machine-like command-line based HTTP clients (e.g. curl or wget). If you are interested in a Human-to-Machine interface, please visit distributions.aeronomie.be.

The idea is that you write a script which recursively loops through the data to examine on each level which further levels are available for downloading.

Starting on the top-level, you see the available projects. (The responses in the examples are truncated, the full list of projects is below).

Tropospheric NO2 and aerosols with MAX-DOAS measurements in Uccle

Distribution of tropospheric NO2 and aerosols with MAX-DOAS measurements in Uccle, Belgium

Dual-scan ground-based multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements of tropospheric nitrogen dioxide (NO2) and aerosols were carried out in Uccle (50.8° N, 4.35° E; Brussels region, Belgium) for 2 years from March 2018 to February 2020. The MAX-DOAS instrument operated in both UV and visible wavelength ranges in a dual-scan configuration consisting of two sub-modes: (1) an elevation scan in a fixed viewing azimuthal direction and (2) an azimuthal scan in a fixed low elevation angle (2°). By analyzing the O4 and NO2 differential slant column density (dSCD) in six different wavelength intervals along every azimuthal direction and by applying a new optimal-estimation-based inversion approach presented in Dimitropoulou et al. 2022, the horizontal distribution of the NO2 near-surface concentrations and vertical column densities (VCDs) as well as the aerosol near-surface extinction coefficients are retrieved along 10 azimuthal directions. This dataset represents the differential slant column density data to perform both the normal MAX-DOAS vertical profile retrieval from the elevation scans, as well as the horizontal profile using the azimuthal scans, by applying the method presented.

L2 SEMPAS Zeebrugge

L2 data from the SEMPAS instrument in Zeebrugge, Belgium

L2 data (multiple species, differ per data type) from the SEMPAS instrument during its on-shore test campaign in the port of Zeebrugge, Belgium. This data is used to infer the results presented in Mettepenningen et al., *SEMPAS: A UV-visible Spectroscopy Instrument for Monitoring Shipping Emissions and Atmospheric Composition on the North Sea*, in prep.The dataset contains three data types: - Shipping emission measurements: L2a slant column densities of NO$_2$, SO$_2$ and O$_4$ for a selection of measured ships that passed the instrument throughout the campaign period. The selection is based on the cases as described in the paper. Additional static and dynamic shipping information is given in the same file as the measurements, taken from an AIS receiver on the instrument. - Atmospheric measurements: L2a slant column densities for NO$_2$, SO$_2$, HCHO and O$_4$ as processed through the QDOAS software, provided for the full campaign period. - FRM4DOAS data: the L1 data has been directly processed through the operational FRM4DOAS framework. This creates L2b vertical column densities and concentration profiles of NO$_2$ and HCHO, provided for the full campaign period.

BRAMS wav data

Raw WAV data from the BRAMS network

##Description of the networkBRAMS (Belgian RAdio Meteor Stations) is a meteor radio forward scatter network located in Belgium and neighboring countries. The transmitter is located in Dourbes and emits a Continuous Wave (CW) circularly polarized signal at a frequency of 49.97 MHz and with a power of approximately 340 Watts. Receiving stations use a 3-elements Yagi antenna set up vertically and either an analog (ICOM-R75 or AR5001) or SDR (RSP2 or RSPDx) type receiver. Signals from the antenna are combined with a signal produced by the BRAMS calibrator at 49.9705 MHz before entering the receiving chain. Sampling frequencies are 5512 Hz (for analog-type receivers) or 6048 Hz (for SDR-type receivers). Data are coded on 16 bits. Local Oscillator of the receivers is set up at 49.969 MHz such that beacon signal appears at 1 KHz and calibrator signal appears at 1.5 KHz. ICOM-R75 are not stabilized in frequency so beacon and calibrator frequencies can slowly drift in time. BRAMS data are synchronized using PPS (Pulse Per Second) coming from GPS data.##Raw data formatRaw data are saved in WAV format. Size of a single WAV file is approximately 3.3 MB. Metadata are saved in custom chunks: * BRA1 contains information about sampling rate, local oscillator frequency, start of the file, number of PPS, beacon latitude, longitude and altitude, frequency, power and polarization of the transmitter, ID latitude, longitude and altitude of the receiving antenna, code of the transmitter (BEDOUR) and of the receiving station (e.g. BEOUDS). * BRA2 contains the PPS##Filename formatFilenames format : RAD_BEDOUR_20260530_0000_BEJALH_SYS001. First 3 characters refer to radio observations, characters 5 to 10 refer to the transmitter code, characters 12 to 19 and 21 to 24 refer to the observing time, characters 26 à 31 refer to the receiving station code, and characters 33 to 38 refer to antenna ID.Data are aggregated by day and per receiving station as ZIP files.

UV-Index GUV Data

UV-VIS solar irradiance monitoring in Belgium until 2016

Between 1993 and 2016, BIRA-IASB maintained 6 stations in Belgium for the monitoring of the ground-based solar irradiance, mainly in the UV spectral range. The proposed data from this network are those obtained with multi-channel filter radiometers (GUV-2511) manufactured by [BIOSPHERICAL Inc](https://www.biospherical.com/).The time period is limited to 2011-2015. It corresponds to measurements of downwelling global solar irradiance at the following wavelengths: 305 nm, 313 nm, 320 nm, 340 nm, 380 nm and 395 nm, as well as Photosynthetically Active Radiation (PAR - 400-700 nm). A readme file available here describes the format of the data and datafiles.
