Welcome to GRiMS

Global & Regional Integrated Monitoring System

WELCOME to the GRiMS (Global and Regional Integrated Monitoring System) program. This system is designed to provide continuous monitoring of the ionosphere, detecting and tracking any anomalies on a daily basis. It is a critical tool for scientists and researchers who rely on accurate and up-to-date information about the state of the ionosphere.

THE GRiMS program comprises two main modules: the Global and Regional programs. The Global program is responsible for monitoring the ionosphere on a global scale, collecting data from around the world to produce a comprehensive overview of ionospheric activity. The Regional program, on the other hand, focuses on specific areas of interest (Currently only Turkey), providing detailed information about the ionosphere in specific regions.

ONE of the primary benefits of the GRiMS program is the ability to access anomaly maps. These maps are generated through various processes, providing valuable insight into the state of the ionosphere at any given time. From the GRiMS menu, you can easily access these maps and stay informed about the latest developments in ionospheric activity.

GRiMS is the product of a collaborative effort between individuals from various scientific disciplines. The system undergoes constant updates and improvements to ensure its accuracy and effectiveness. Currently, a live version of the system is available for testing, development, and ongoing updates.

The current version of GRiMS provides the following tasks:

• Daily presentation of global anomaly maps using rapid CODE GIMs until indices/parameters are published from OMNIWeb. Since the OMNIWeb data arrives with a delay, there is a section where the user can review the current indices/parameters from other data sources. Then the presentation of hourly anomaly maps based on the final CODE-GIMs with indices/parameters. Thus, it is possible to observe anomaly regions that may be caused by many factors such as space weather conditions.
• Observing the global anomaly regions and station-based details.
• The use of suitable IGS stations from regions where the anomaly is above 5 TECU (above the accuracy level of CODE-GIM (~2/3 TECU)) and lasts longer than 8 hours (abnormal day condition stated by Liu et al. (2009)).
• Identification of stations with the highest anomaly in the northern and southern hemisphere high latitude, mid-latitude, and equatorial regions.
• Obtaining station-based VTEC values, and thus graphical presentation of anomalies with higher accuracy using the Moving Average (MA), Highest Density Interval (HDI), and Autoregressive Integrated Moving Average (ARIMA) methods.
• Presentation of daily Jason Altimeter VTEC maps for ocean regions.
• Daily presentation of regional anomaly maps using CORS and IGS stations.
• The user has the option to download global and regional anomaly maps and various data. Additionally, they can request data processing for their desired date and have the results sent to their provided email addresses.

The system is currently undergoing continuous development, and we highly value user feedback. We appreciate the input provided in advance.
