Virtual Solar Observatory

Search for Solar Physics Data Products:

If you're new to the VSO, see How To Search, the FAQ or click the ? icons for online help.

Please select which values you wish to use to search for data products:

Time: Search by time interval.; Derive time intervals from event catalogs
Observable: Search based on physical observables?
Instrument / Source / Provider: Search based on instruments? or data archives?; Instrument / Source (not provider dependent); Instrument Only (not source or provider dependent)
Spectral Range: Search based on a spectral range
Nicknames: Search based on common terms used to describe data products; Note: Nicknames generate an intersection with other search terms, so searching for a nickname, and a physical observable (or other parameter) when a nickname defines other physical observables will result in no matches.; Show Nickname Definitions

Setting Default Values:

Note -- you'll need to set build=1 and select a server.

Time

timerange=YYYY[MM[DD[HH[mm]]][-YYYY[MM[DD[HH[mm]]]]]

eg. timerange=20031230-200402041230

Nickname

nickname=nickname1[&nickname=nickname2]

eg. nickname=UV%20image&nickname=Full-disk%20dopplergram

eg. nickname=UV%20image&nickname=Full-disk%20dopplergram&nickname_long=1

Physical Observable

physobs=physobs1[&physobs=physobs2]

eg. physobs=LOS_velocity&physobs=particle_flux

Spectrum

wave=wavename[&wave=wavename2] or waverange=min[-max]unit

eg. wave=softXR&wave=visible&waverange=50GHz

eg. wave=EUV&waverange=100-1000Angstrom

Instrument / Source / Provider

Note -- You also need to make sure either instrument=1 or provider=1 is set, or it won't display that section

(well, actually, instrument=x will turn on instrument, but provider=y won't turn on provider)

Other note -- No warnings are generated if a term does not 'work' to select something (as with physobs and nickname)

Instrument: instrument=[[provider.]source.]instrument; Also possible: an asterisk for the source (preparing for STEREO) : instrument=SSC.*.SECCHI; eg. instrument=MDI&instrument=SOLIS.vsm; eg. instrument=MDI&instrument=SOLIS.vsm&provider=1; eg. instrument=SDAC.SOHO.MDI&instrument=NSO.*.vsm; eg. instrument=SDAC.SOHO.MDI&instrument=NSO.*.vsm&provider=1
Source: source=[provider.]source; eg. source=SOHO&source=OBSPM.Nancay&instrument=1; eg. source=SOHO&source=OBSPM.Nancay&provider=1
Provider: provider=provider; eg. provider=NSO&provider=HAO&instrument=1&; eg. provider=NSO&provider=HAO&provider=1
