Information on Service 'Alma-Ata Station Neutron Monitor Data Service'

[Use this service from your browser]

Further access options are discussed below

The Alma-Ata Cosmic Ray Station operates the 18NM-64 neutron supermonitor at an altitude of 3340 meters above sea level, with a geomagnetic cutoff rigidity of 6.7 GeV. The station provides real-time, minute-level measurements of cosmic ray intensity, contributing to the international NMDB network. These data support the study of cosmic ray variations and space weather phenomena.

The provided dataset consists of daily tables, where each table corresponds to a single observation day. The data includes two columns:

The data are collected and provided by the Institute of Ionosphere, (https://ionos.kz/) and are also available through the Kazakhstan Space Weather Portal (https://ssa.fai.kz/, registration required), which additionally offers interactive visualizations and graphs.

Overview

You can access this service using:

This service is published as follows:

local means it is listed on our front page, ivo_managed means it has a record in the VO registry.

Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

NameTable Head DescriptionUnitUCD
counts Count Average neutron counts per second, derived from one-minute measurements. ct/s arith.rate;phys.particle.neutron
obs_time Timestamp Time of observation in UTC (yyyy-mm-ddThh:mm:ssZ). N/A time.epoch

Default Output Fields

The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

NameTable Head DescriptionUnitUCD
counts Count Average neutron counts per second, derived from one-minute measurements. ct/s arith.rate;phys.particle.neutron
obs_mjd Obs. MJD Time of observation in MJD. d time.epoch
obs_time Timestamp Time of observation in UTC (yyyy-mm-ddThh:mm:ssZ). N/A time.epoch

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
