The following special issues are scheduled for publication in ANGEO:

Space weather connections to near-Earth space and the atmosphere
15 Jan 2017–30 Jun 2017 | Guest editors: M. Abdu, A. Dal Lago, R. A. Buriti, J.-P. Raulin, and C. Jacobi | Information

Issue goals:

The main goal of the special issue is to publish papers presented during the last Brazilian meeting of Space Geophysics and Aeronomy that was held in September 2016 in Jataí, Goiás, Brazil. We intend this special issue as an important contribution to the development and future of space and atmospheric sciences in Brazil. Further, we expect to contribute to these fields with new advanced research released recently by Brazilian researchers and their collaborators from other countries. However, contributions from other parts of the world are welcome.

Call for papers:

We invite researchers to contribute to the special issue "Space weather connections to near-Earth space and the atmosphere" by submitting papers of recent research in the fields of space science and aeronomy. This issue covers many aspects of Sun—Earth relations, which include space weather, heliophysics, magnetospheric and upper-atmospheric physics, and processes, dynamics and structures of the neutral atmosphere.

The Earth's magnetic field: measurements, data, and applications from ground observations (ANGEO/GI inter-journal SI)
01 Nov 2016–03 Mar 2017 | Guest editors: J. Rasson, A. Gonsette, K. Arora, A. Chulliat, C. Turbitt, and G. Balasis | Information

This special issue addresses open research topics related to ground observations of the Earth's magnetic field. It consists of papers based on talks given during the XVIIth IAGA Workshop on Geomagnetic Observatory Instruments, Data Acquisition and Processing that was held in Dourbes (Belgium) from 4 September to 10 September 2016. Ground magnetic observatories are important for geomagnetism. They provide fixed, long-term, high-quality global time series, thus helping the scientific community to understand the geophysical processes of solid Earth as well as the interaction of the Sun with Earth's magnetosphere and ionosphere. Data users such as space weather, space physics, and geomagnetic field modelling communities always require better quality data from observatories for their applications. This workshop aimed to improve observatory practice especially when faced with new challenges like advanced instrumentation development, higher sampling rates, faster definitive data processing, real-time delivery, and remote deployment. The event was successful in bringing together about 90 attendees from 37 different countries, of which 21 were European. The 72 presentations covered topics such as instrumentation, observation techniques and processing, data transmission, and applications. We invite the workshop participants and other researchers to submit their results to this inter-journal special issue of Annales Geophysicae (ANGEO) and Geoscientific Instrumentation, Methods and Data Systems (GI).

Advanced Global Navigation Satellite Systems tropospheric products for monitoring severe weather events and climate (GNSS4SWEC) (AMT/ACP/ANGEO Inter-Journal SI)
01 Nov 2015–31 May 2018 | Guest editors: V. Kotroni, J. Jones, S. de Haan, E. Pottiaux, O. Bock, R. Pacione, and R. Van Malderen | Information

Since 1990, signals from global positioning system (GPS) satellites have been recorded by networks worldwide. From these GPS observations the zenith total delay (ZTD) can be computed. Using surface measurements of pressure and temperature, these ZTD values can be turned into water vapour amount and used for atmospheric research. The main aim of the COST action ES1206 “Advanced Global Navigation Satellite Systems tropospheric products for monitoring severe weather events and climate” (GNSS4SWEC) is to coordinate the research and the development of new, advanced tropospheric products derived from GNSS signal delays, exploiting the full potential of multi-GNSS (GPS, GLONASS and Galileo) water vapour estimates on a wide range of temporal and spatial scales, from real-time monitoring and forecasting of severe weather to climate research. The potential impacts of this work are great: improved severe weather forecasting, leading to a decreased risk to life and national infrastructure; improvement of climate projections also has major global significance. In addition the action will promote the use of meteorological data in GNSS positioning, navigation, and timing services.

The main topics envisioned in the special issue include the following:

  • The development of advanced and new GNSS tropospheric products related to
    • multi-GNSS constellation signals for water vapour remote sensing,
    • water vapour anisotropy (horizontal gradients, satellite slant delays, tomography, etc.),
    • real-time/ultra-fast water vapour remote sensing in support of nowcasting ,
    • improvement of the temporal and spatial resolution capability of GNSS water vapour remote sensing.
  • The exploitation of these products in numerical weather prediction (NWP) and nowcasting, such as
    • the development of new initialization/assimilation methods in NWP,
    • the development of forecasting tools (water vapour maps, convective indexes, alarm systems, etc.) for nowcasting and severe weather events.
  • The assessment of these GNSS tropospheric products (see first point) derived from a common benchmark reference data set.
  • The assessment of the standardized methods/tools for NWP/nowcasting (see second point) based on the GNSS products built on the benchmark data set.
  • Exploiting re-analysed/reprocessed GNSS tropospheric products for climate studies:
    • comparison/assimilation in the regional/ global climate models,
    • comparisons with other in-situ, ground-based and satellite water vapour retrievals,
    • development and assessment of homogenization methods for GNSS-based product time series,
    • analysing the variability and trends in GNSS-based water vapour retrievals.
  • Establishment of new GNSS analysis centres for monitoring the atmosphere.

Submissions of papers dealing with broader GNSS4SWEC objectives are also encouraged:

  • synergy between GNSS and GNSS radio occultation (RO),
  • monitoring the other components of the hydrological cycle (soil moisture, snow cover, terrestrial water storage) with GNSS.
