Location (town, country): Roquetes, Spain

Description of the infrastructure:

OE infrastructure consists of several geophysical observatories in Spain and in the Antarctic Spanish Base, with more than a hundred years-long data records being significant data contributor to international databases making data, historical and real-time, standardized and available to the near-space community for their research, applications and modelling purposes. The OE have developed climatologic ionospheric models and ionospheric disturbance models bounded to the configuration and variation of the Interplanetary Magnetic Field.

OE team hosts the largest Spanish Ionospheric database, covering the period from 1955 to present. OE team operates a DPS4D system for specific HF experiments probing the ionosphere. In addition to the routine ionospheric measurements, the OE DPS4D performs oblique drift measurements in synchronous operation with other DPS4D systems for the detection of Doppler and angle of arrival perturbations inferred by TIDs.

Services currently offered by the infrastructure:

OE infrastructure located at Ebro Observatory offers real time VI ionograms and skymaps at 5 min sampling, and daily variations of the drift velocity measurements and directograms refreshed every 5 minutes. It sends real time data to international databases such as GIRO, DIAS, TechTIDE and it also offers access to their ionospheric database starting from 1955. OE also provides ionospheric day to day variability and hourly manually revised ionograms. It hosts the International Service on Rapid Magnetic Variations, responsible for creating and publishing the lists of rapid variations (SFE and SC) and provide several Space Weather products such as geomagnetic local K index and ionospheric uplift predictions. Moreover, OE provides VI ionograms during the austral summer months from the ionosonde in the Spanish Antarctic Base

OE systems are accessed remotely by 6500 users per year and about 1800 participants per year attend events organized in situ. According to Google Scholar over 1900 papers make reference to the Ebro Observatory geomagnetic and ionospheric data, over 600 makes reference to ionospheric data.

New areas opening to users:

  • HF D2D experiments to improve ionospheric specification in Europe.
  • Identification and specification of Large Scale Travelling Ionospheric Disturbances.
  • Identification and specification of Plasma Depletions.
