| description | Solar observation data downloader for SDO, STEREO, and Solar Orbiter missions. Use when Claude needs to: (1) download SDO/AIA EUV data from JSOC, (2) download STEREO/SECCHI/EUVI data, (3) download Solar Orbiter/EUI/FSI data, (4) create multi-date time series of solar observations, (5) pair multi-wavelength observations. Triggers: 'solar data download', 'SDO download', 'AIA data', 'STEREO data', 'Solar Orbiter data', 'FITS download', 'sun observation data', 'EUI data', 'EUVI data', '태양 데이터 다운로드', '태양 관측 데이터' |
SSW-Download
Download solar observation data from multiple space missions using ssw-tools (https://github.com/sswlab/ssw-tools).
Setup
pip install git+https://github.com/sswlab/ssw-tools
Supported Missions
| Mission | Instrument | Wavelengths | Function | Source |
|---|
| Solar Orbiter | EUI/FSI | 174A, 304A | run_solo() | SOAR (no registration) |
| STEREO-A/B | SECCHI/EUVI | 171A, 304A | run_stereo() | VSO (no registration) |
| SDO | AIA | 94,131,171,193,211,304,335A | SunPy Fido | JSOC (free registration required) |
Quick Start
Solar Orbiter (EUI 174A + 304A pair)
from ssw_tools.download_data.solo_down import run_solo
from datetime import datetime
sd = datetime.strptime("2024-06-01T00:00", "%Y-%m-%dT%H:%M")
run_solo(sd, None, delta_hours=12, out_path='./solo_data/',
level=1, tolerance_min=15, cadence_min=1440)
STEREO (EUVI 171A + 304A pair)
from ssw_tools.download_data.stereo_down import run_stereo
from datetime import datetime
sd = datetime.strptime("2024-06-06T00:00", "%Y-%m-%dT%H:%M")
run_stereo(sd, None, delta_hours=12, out_path='./stereo_data/',
level=1, tolerance_min=15, cadence_min=1440)
SDO/AIA (via SunPy Fido)
from sunpy.net import Fido, attrs as a
import astropy.units as u
result = Fido.search(
a.Time('2024-01-01T00:00', '2024-01-01T00:01'),
a.jsoc.Series('aia.lev1_euv_12s'),
a.jsoc.Wavelength(193*u.AA),
a.jsoc.Segment('image'),
a.jsoc.Notify('your@email.com')
)
files = Fido.fetch(result, path='./sdo_data/')
Parameters
| Parameter | Description | Default |
|---|
start_date | Search start (datetime) | required |
end_date | Search end (None = same as start) | None |
delta_hours | Search window +/- hours | 12 |
out_path | Output directory | required |
level | Processing level (1 or 2) | 1 |
tolerance_min | Max gap between wavelength pairs | 15 |
cadence_min | Time step for series (1440=daily) | 1440 |
