# Introduction The SDO data center is dedicated to the acquisition of SDO/AIA and SDO/HMI data from the Joint Science Operations Center (JSOC) located in Stanford, and the subsequent provision of the data throughout Europe. In 2015 the SDO data center was completely refurbished. Brand new database, storage, and web servers were bought, bringing its hardware up to date with current technology. The center was equipped with 160TB of usable storage, out of which 100TB is reserved for the SDO mission. This change in hardware was coupled with a change in the software for data acquisition, redistribution, and user access, which was completely rewritten and runs now independently from the netDRMS software provided by the JSOC. With the SDO mission gathering a huge archive of useful data, we decided to shape our service on the efficient provision of data on demand rather than on the latest available data. # Data Access ## Access SDO data via a web application - [Wizard](/wizard) The wizard is a simple web application to search and download SDO data. Search, select and export the data you want. The data will be prepared and made available through [FTP](ftp://sdo.oma.be/exports). Or if you are a ROB scientist, you can access the data directly on yama under /data/SDO/exports. *By default user are only allowed to request up to 50GB of data, and it will stay available for a minimum of 60 days. if this is not sufficient for your needs, please contact sdoadmin@oma.be for help.* ## Watch & access the last 24h of AIA data - [Latest](/latest) You can watch videos of the lasts 24 hours of SDO quiclook data. You can also access the images and the original FITS files themeselves. Or if you are a ROB scientist, you can access the data directly on yama under /data/SDO/AIA_quicklook # Access a 1 hour synoptic set of AIA and HMI data - [FTP](ftp://sdo.oma.be/AIA_HMI_1h_synoptic) AIA in the 10 wavelengths (for level 1), and HMI magnetogram and continuum data, at full resolution (4096x4096) and at a cadence of 1 hour is accessible via FTP. Note that HMI data is not available since August 2018 because of an anomaly in the instrument. See http://jsoc.stanford.edu/jsocwiki/HMI2018AugustAnomaly Or if you are a ROB scientist, you can access the data directly on yama under /data/SDO/AIA_HMI_1h_synoptic ## Access a 2 minutes synoptic set of AIA data - [FTP](ftp://sdo.oma.be/AIA_2m_synoptic) AIA level 1.5 data in the wavelengths 94Å and 211Å at a reduced resolution (1024x1024) and at a cadence of 2 minutes is accessible via FTP. Or if you are a ROB scientist, you can access the data directly on yama under /data/SDO/AIA_2m_synoptic ## Access SDO data via IDL and the VSO & SolarSoft library You can search and download AIA & HMI data from IDL through the VSO with the [SolarSoft library](https://www.lmsal.com/solarsoft/), see the [tutorial on how to search and download data](./vso_idl.html) and [examples how to make videos for AIA or HMI](./sdo_video_idl.html). ## Access SDO data via Python & SunPy You can search and download AIA & HMI data via Python by using the [SunPy library](https://sunpy.org/), see the [tutorial on how to search and download data](https://docs.sunpy.org/en/stable/generated/gallery/acquiring_data/searching_vso.html), and the [tutorial on how to request cutouts of AIA images from the JSOC](https://docs.sunpy.org/en/stable/generated/gallery/acquiring_data/downloading_cutouts.html) # Meetings and Presentations Some of the information below is now obsolete and is kept for archiving reasons. - [STCE workshop on 'Accessing and Exploitation of SDO data at STCE'](./STCE2011workshop.html), held on May 23, 2011 - [Soteria Capacity Building Workshop](https://www.sidc.be/users/boyes/SDOSSW/soteria_feb_2011.pdf), held on February 15, 2011 - [3rd SDO pipeline meeting](./Meeting20100917.html) held on September 17, 2010 at ROB - [COSPAR 2010 presentation of David Boyes](https://www.sidc.be/users/boyes/cospar10_slides.ppt) - [Distributing and mining SDO data in Europe](./uploads/SDO_HO_COSPAR2010_SDODistibutingMining_SP_VAD20100725.pptx), talk at COSPAR 2010 by S.
