AIA data from May 13, 2010 onward have been processed to level 1.
However, there is a four day lag for current AIA data to be processed to level 1 final.

| AIA and HMI impose novel requirements
on the data processing and distribution. The volume of data places
constraints on the frequency of reprocessing and redistribution of
data. The uniform character of the data products permit users to
access data by "observing the archive"-- making data requests for
specific location, resolution, cadence, etc. much like the observing
plans for previous high-resolution instruments such as TRACE and
Hinode/SOT. Here we layout the plan for data processing and
distribution that combines these two elements. When referring to AIA
data, we include HMI intensity and longitudinal magnetograms, since
they are integral parts of the AIA investigation. Detailed
descriptions of AIA data can be found in AIA
plan for producing and distributing data. More information on
AIA data can be found on the LMSAL SDO Documentation
page and details on other data and science tools supported by
LMSAL can be found on Sungate.
The
SDO Data Analysis Guide describes tools for identifying appropriate AIA
data for scientific analysis and for accessesing and analyzing these
data.

| The Heliophysics Events
Knowledgebase (HEK) guides solar and heliospheric
researchers to the most useful times and locations and suggests
reasonable fields of view and durations by providing a means of
search via features and events. This system can be accessed directly
from the web using iSolsearch, through
SolarSoft routines and via web
services. The HEK system tracks data requests using the Heliophysics Coverage
Registry (HCR). You can find datasets associated with
particular events using iSolsearch, or use the HCR to view recent or popular data
requests, or make more
advanced searches for specific datasets. If no datasets that
meet your requirements are available, you can requests cutouts using
the tools in the next section. |

| The primary archive for AIA data is
maintained at Stanford University's Joint Science Operations
Center/Science Data Processing Facililty. The JSOC provides a
web interface for accessing AIA and HMI data, known as lookdata. The AIA team
has developed a means for requesting spatial and temporal subsets of
AIA data as part of the HEK project. You can access this services
either through iSolsearch or directly using the get_aia_data webform. |

| Other groups beyond the core AIA and
HMI science teams have also developed tools for browsing and
searching for SDO data. Most of these leverage the web interfaces
developed as part of the HEK and the JSOC. These include the Virtual Solar Observatory and Helioviewer. |
