Real-Time Database for High Resolution Neutron Monitor
Measurements – RI
NMDB
Summary:
We will set up a European digital repository for cosmic ray data by pooling
existing data archives and by developing a real-time database collecting observations in
the highest time resolution from as many European neutron monitor stations as pos-
sible. Neutron monitors remain the state-of-the-art instrumentation for measuring GeV
cosmic rays. NMDB
will make their data available in real time and in a format that can
be handled by non-experts for use in research (e.g., physics of solar energetic particles)
and space weather forecasting.
Objectives:
h
e combination of neutron
monitors at dif
erent places on the Earth
allows us to measure the spectrum and
anisotropy of relativistic particles from the
Sun and the Galaxy. h
e i
gure on the let
illustrates this, showing that neutron moni-
tors at dif
erent sites respond dif
erently to
a solar energetic particle event.
Neutron monitors also provide key param-
eters for space weather applications, such
as the forecasting of solar energetic particle
events and geomagnetic
storms. h
e i
gure below
shows a map of radiation
hazards in the terrestrial
atmosphere. In order to
make the neutron monitor
network a useful tool for
a broad i
eld of scientii
c
communities, the existing
neutron monitor measure-
ments, which are continu-
ous over several decades,
have to be pooled, and a real-time database has to be developed that collects obser-
vational data from as many European and neighbouring neutron monitor stations as
possible.
Action plan:
h
e objective of NMDB relies on the unii
cation of data acquisition with
dif
erent systems, operated independently by dif
erent groups. h
is will be enabled
through several work packages: (1) architectural design of the database;
(2) establish-
ment of a standard set of rules for data acquisition, and technical preparation of all
participating stations to feed their data into the central database; (3) production of sot
-
ware for data providers to submit data to the database, and for users of the database to
access it by means of commonly used applications and programming languages; (4)
production of tools to enable users to derive key parameters from neutron monitor data
through a user-friendly web interface; (5) production of web-based training material for
non-expert users and students enabling them to understand and use the database, and
dissemination activities to the general public.
Networking activities:
h
e NMDB project gathers the ensemble of active research
groups operating and using neutron monitors in Europe (9 countries), Armenia, Israel,
and Kazakhstan. h
ey will jointly develop concepts and tools to combine their data.
Groups in Mexico, South Africa and the USA have already expressed their interest in
