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('[e-mail]')  # JSOC registered email
)
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

CLI Interface

python -m ssw_tools.download_data.main \
    --target solo \
    --start_date 2024-06-01T00:00 \
    --delta_hours 12 \
    --tolerance_min 15 \
    --cadence_min 1440

Targets: solo, stereo-a, stereo-b
