UN - ARCSSTEE
Space Weather information dissemination hub.
Space weather refers to the conditions in space environment that have impact on space-dependent technological systems. It deals with the interactions of ambient radiation & matter within interplanetary, and occasionally interstellar space.
Space-dependent technologies are technologies which depend on use of satellites that are in orbits.
Space weather is fast becoming a global concern.

Daily Space Weather Nowcast and Forecast
Historically, daily space weather nowcasts started appearing on the platform of www.carnasda.com from 16th January 2018 till 13th January 2023 under the management of the NASRDA Centre for Atmospheric Research. Old files can still be retrieved from the page and here as well.
Henceforth, due to some administrative restructuring and in a bid to promote regional efficiency the space weather casts shall be found here at the UN Regional Centre’s page.
The general public and in particular patrons of space technology-dependent systems/ operations shall benefit tremendously from the space weather now- and forecasts.
Summary of space weather and space weather parameters/observations at the given hours of nowcast and 3-day forecast of daily ionospheric map generated from regional models are as follows:

Total Electron Content (TEC) Nowcast and Forecast
The TEC Model
This is a model developed in Nigeria to forecast the GNSS ionospheric total electron content (TEC) over Nigeria and the entire Africa region.
The NigTEC gives the forecast of the ionospheric condition over Nigeria while AfriTEC give the forecast over Africa.
Here, TEC is shown in form of spatial maps and vidoes for three days.
This is intended for global usage in ionospheric studies.

Africa GNSS TEC Models
The AfriTEC model is a model of the ionospheric GNSS TEC over the entire African region (Longitudes 25 degree West to 60 degree East, Latitudes 40 degree South to 40 degree North). The model can be used .......

Nigeria GNSS TEC Models
The NIGTEC is a model of the ionospheric GNSS TEC over Nigeria (Longitudes 2-15 degrees East, Latitudes 4-14 degrees North) The model can be used to obtain the ionospheric GNSS TEC at all locations over Nigeria.
