Welcome to the Lasp Interactive Solar IRradiance Datacenter or LISIRD website. This data center is currently in its early stages of development. LASP plans to have LISIRD provide convenient interactive access to a comprehensive set of solar irradiance measurements, models, and composite solar irradiance spectra and time series. Click here to begin querying data.

Currently, we have a Data Access Interface that queries data from several LASP missions: SORCE, TIMED SEE, SME, UARS SOLSTICE, and soon SNOE (see graphic below).

We encourage community input to help us make this the most useful site possible. You can help LASP by taking our on-line survey. We also welcome any comments you might have concerning the features, capabilities, and data sets you would like to see provided at this data center.  We will endeavor to take into account the comments and requests we receive in order to make this data center as useful as possible.

Below is a quick-look graphic of current available measurements (by clicking on different regions of the graphic, you will be taken to that dataset):

In order to maximize the accessibility and usability of solar irradiance data and information from multiple missions, LASP has initiated the process of developing a data center (LISIRD) to better serve the needs of researchers, educators, and the general public.  This data center will provide users access to information about solar irradiance, as well as interactive and direct access to a comprehensive set of solar spectral irradiance measurements from the soft X-ray (XUV) at 0.1 nm up to the near infrared (NIR) at 2700 nm, as well as state-of-the-art measurements of Total Solar Irradiance (TSI).  LASP researchers are also responsible for an extensive set of solar irradiance models and historical solar irradiance reconstructions, which will also be accessible via this data center.

The objectives for this system are to provide a centralized and convenient way for a variety of users to access solar irradiance information and data products. Some of the features of this system will include:

• Management and availability of research-quality data sets to researchers and the general public, free of charge.
• Navigational interfaces to support the identification of available products, services, and tools
• Convenient access to at least the following data sets:

• Also made available will be
  • Solar indices for space weather operations
    • H I Lyman Alpha 121.6 nm
    • Mg II core-to-wing
    • He II 30.4 nm
    • Fe XVI 33.5 nm, 0.1-7 nm
  • Solar irradiance spectral and variability models
• Provide data products to users in a variety of data formats and by a variety of access mechanisms.  Access mechanisms being investigated include:
• Quick Access (prepared plots, thumbnails, data files; FTP, etc.
• Interactive Access (WWW-based, interactive subsetting, exploring, plotting)
• Automated Access (support for batch updates by users, subscription and automated delivery capability)
• Direct Access
• Via programming APIs (IDL, Java, other?) such that products appear as if they are on the user’s own computer already
• Access to near realtime products (e.g. solar indices)
• Support existing data access systems/tools, e.g. the Virtual Solar Observatory (VSO)
• Software library of tools for analysis, data manipulation, and translation

LASP is now in the early stages of developing the capabilities that this system will provide. In the mean time, we offer some basic information and links to enable this site to be used as a portal to other existing web sites and data services.  Development of this system will initially focus on the core functions of data query and retrieval, as well as data discovery resources to enable identification of desired data.  Resident data sets will also become available via the Virtual Solar Observatory (VSO) in the near future.

Please check back in the future for additional capabilities, or feel free to join our email list, and we will be happy to notify you when additional capabilities are available.  Your information will only be used for this purpose.
