PCEEJ Equatorial Electrojet Model data for years 2003-2010 and 2014-2018

This dataset comprises the PCEEJ equatorial electrojet model current intensity values (mA/m). The PCEEJ is an empirical model based on the principal component analysis of satellite and ground equatorial electrojet data, described in detail in Soares et al. (2022), to which this data publication is supplement to. The model data is provided as text files (.csv extension) and Matlab-formatted files (.mat extension). For text files, there is one file per year (file name labeled with the corresponding year). For the Matlab format, there is only one Matlab file that contains all years as separate variables (variable name labeled with the corresponding year). Each yearly file/variable corresponds to a matrix: the rows represent local time/longitude bins and the columns represent days of year. The local time/longitude bins (rows) always sum up to 432 (12 local time intervals and 36 longitude intervals). The day of year (columns) always starts in January 1st and ends in December 31st, leading to a total of 365 or 366. The PCEEJ model values of 13 years from 2003 to 2010 and from 2014 to 2018 are provided. The PCEEJ basis functions (principal components) are provided in the text and Matlab files labeled as ‘PC_Functions’. The ‘PC_Functions’ data is given as a 432x10 matrix, in which 432 stands for the aforementioned local time/longitude bins and 10 represents the 10 principal components used to obtain the PCEEJ model (in ascending order). Two additional auxiliary indices, namely ‘lt_index’ and ‘lon_index’ are also contained as text and Matlab files. These indices represent the corresponding local time and longitude values of each row of the PCEEJ yearly files and ‘PC_Functions’ files.

Magnetometer station Macapa, Brazil, calibrated 1-second geomagnetic data.

This dataset contains 1-second geomagnetic vector and scalar data from the magnetometer station Macapa. The data is from 15-Nov-2019 to 07-Dec-2019, from 07-Feb-2020 to 05-Apr-2020, and from 09-Oct-2020 to 21-Nov-2020. The data files follow the IAGA-2002 data format. The IAGA format description is copied from https://www.ncei.noaa.gov/services/world-data-system/v-dat-working-group/iaga-2002-data-exchange-format and from https://www.ncei.noaa.gov/sites/default/files/2022-07/IAGA%202002%20July%202003%20Revision.txt. Both documents were downloaded on 2024-08-11 and are available here as IAGA_2002_file_format_description_2024-08-11.pdf. The data themselves are described in Mendel Martins et al. (2024).

Intermagnet Reference Data Set (IRDS) 2017 – Definitive Magnetic Observatory Data

Definitive digital values of the Earth's mangetic field recorded during 1991 and 2017 at INTERMAGNET observatories around the world. Data includes minute, hourly and daily vector values, along with observatory baseline values for quality control. Annual means are also included. All data is included on the single downloadable archive file (gzipped tar format) available from this landing page. This is the 24th annual publication in the series. Some national data institutions may have related DOIs that describe subsets of the data. These DOIs are shown under "Related DOIs to be quoted". For more information on the data formats used in this publication and the technical standards used to create the data, please refer to the INTERMAGNET Technical Manual.

Data includes minute, hourly and daily vector values, along with observatory baseline values for quality control. Annual means are also included. All data is included on the single downloadable archive file (gzipped tar format) available from this landing page. This is the 25th annual publication in the series. Some national data institutions may have related DOIs that describe subsets of the data. These DOIs are shown under "Related DOIs to be quoted".

Intermagnet Reference Data Set (IRDS) 2018 – Definitive Magnetic Observatory Data

Definitive digital values of the Earth's mangetic field recorded during 1991..2018 at INTERMAGNET observatories around the world. Data includes minute, hourly and daily vector values, along with observatory baseline values for quality control. Annual means are also included. All data is included on the single downloadable archive files. This is the 28th annual publication in the series. Some national data institutions may have related DOIs that describe subsets of the data. These DOIs are shown under "Related DOIs to be quoted". Beginning with the publication of the definitive data for 2015, INTERMAGNET stopped publishing individual years of data and started publishing the entire, cumulative definitive data set since INTERMAGNET’s first recorded definitive data in 1991. This data set is known as the "INTERMAGNET Reference Data Set" (IRDS). The IRDS comprises all INTERMAGNET one-minute definitive data since 1991 and is annually updated with a new year and occasional corrections to previous releases. Some national data institutions may have related DOIs that describe subsets of the data. These DOIs are shown under "Related DOIs to be quoted". File names for IRDS data are formatted in the form mag<year>_def<year>.zip. The mag<year> section of the filename describes the year in which the data was recorded. The def<year> section of the filename describes the most recent annual INTERMAGNET publication in which the data was updated. Files where mag<year> = def<year> have had no corrections since their original publication. For example, "mag2015_def2016" indicates that this file is different from the first release "mag2015_def2015".
