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
