T96 Parameters Downloader

This script downloads 1 hour interval data from omni2 spacecraft (dataset) from OmniWeb. Data is valid for interval 1.1.1968 untill newest available data.

Requirements

To run the script you need Python and pip installed. This script was developed with Python 3.10.6, but it might work with earlier versions. To install the required packages just run pip3 install -r requirements.txt.

Run instructions

If you have all the requirements, you just need to run python3 ./pull_parmod.py

Output file description

The script creates the following files in the current directory when run:

parmod_new_intermediate.dat this file contains intermediate products straight from OmniWeb. Missing values are indicated by value 999.9 in the case of the intensity of y and z components of the interplanetary field, 99.99 in the case of pdyn, and 99999 in the case of Dst index. This file contains the following columns:
1. year specifying the year;
2. month specifying the month;
3. day specifying the day;
4. hour specifying the hour;
5. doy specifying the Day of Year;
6. By intensity of y component of the interplanetary field;
7. Bz intensity of z component of the interplanetary field;
8. pdyn dynamic pressure of solar wind (in nPa) at a given date and time;
9. Dst index (in nT).
parmod_new_interp.dat this file contains linearly interpolated intermediate data with an indication of which values were missing. The file format is the same as in the parmod_new_intermediate.dat with an additional column that contains an ASCII encoded decimal value which is the result of bitwise or (or numerical add) operation of values representing missing columns before interpolation where the following values have the following meaning:

- `0000 0100` (4) - a value of `By` was missing and the current value in the appropriate column was computed by linear interpolation;
- `0000 1000` (8) - the value of  `Bz` was missing and the current value in the appropriate column was computed by linear interpolation;
- `0000 0010` (2) - the value of  `pdyn` was missing and the current value in the appropriate column was computed by linear interpolation;
- `0001 0000` (16) - the value of  `Dst` was missing and the current value in the appropriate column was computed by linear interpolation.
