Release Notes for Giovanni 4.6

Giovanni 4 is the next generation of Giovanni, designed to be faster, more interactive and easier to learn than its predecessor.

Giovanni 4.6 consists of the following key features:

New! in Giovanni 4.6

  • Download images in TIFF format
  • Vector plots of GSSTFM Wind Stress

Available data variables

  • Aerosol Optical Depth and other aerosol measurements from MISR, MODIS and OMI instruments, and from the GOCART model
  • Rainfall from TRMM 3B42
  • Heat Flux and Wind Stress  from GSSTFM
  • Temperature and Humidity profiles from AIRS

Known Issues in Giovanni 4.6

New for Giovanni-4 vs. Giovanni-3

  • Interactive maps supporting zoom and pan
  • Interactive linked scatterplot + map, both individual points and time-averaged grid points
  • Vector grid maps, shown as arrows
  • Faster (much!) services

New User Interface

The User Interface is being redesigned to be less opaque to new and occasional users.  It also allows users to narrow down variables for selection either by selecting particular attributes ("faceted browsing") or filtering on keywoards.  However, experienced Giovanni users may see some "user interface shift shock". In some cases, certain things may seem more difficult or tedious to do than in Giovanni 3.  Please tell us those things, with particular reference to how you used to do them in Giovanni 3!  We may also be able to provide some short cuts (e.g., Bookmarkable URLs below).

Bookmarkable URLs 

Bookmarkable URLs allow you to save URLs in order to re-run the exact same workflow at any future date. These can also be used to save partially filled in forms, acting as a kind of template for common analysis operations.

 

Known Issues

This release of contains some bugs, some known (see Known Issues below), and some not yet known.  Please send us feedback using the Feedback button.  

Browser Compatibility

  • iPad:  Giovanni 4 does not yet run on iPad/iPhone Safari.
  • Safari and Chrome on Mac:  Scrollbars for the facets on the right do not show up for some Mac browsers (Safari, Chrome), unless scrollbars are set to Always in the System Preferences -> General of the Mac.

User Interface

  • When a data variable is selected, if the date range of the data is on the first of the month, the start date widget highlights the end of the previous month instead.
  • For large result maps that require vertical scrolling, shift+click for zooming to selected regions does not work correctly.
  • Parts of borderlines on maps are missing at certain zoom levels.

Map (Time Averaged)

  • If the selected bounding box is oriented towards east and crosses both 0 and 180 deg meridian, the plots are not rendered correctly. The data is valid.

Interactive Scatter Plot

  • Plot downloads for the scatter plot sometimes render poorly with text continuing off the plot.

Time Series Plot

  • Time series plot options for variables of the same quantity type (e.g. – precipitation, aerosol optical depth, temperature) need to be set to the same values in order to ensure that all plots get the right y-axis range.

  • When plot options are changed the options page does not disappear when the Re-Plot button is clicked. The user needs to click again on the Plot link on the right under History.

Scatter Plot

  •  When plot options are changed the options page does not disappear when the Re-Plot button is clicked. The user needs to click again on the Plot link on the right under History.

Animation

  • Animation’s ‘Go To’ field does not respond to the Enter key in Internet Explorer. Clicking outside the text field triggers the correct frame change.

  • If the selected bounding box is oriented towards east and crosses both 0 and 180 deg meridian, the plots are not rendered correctly. The data is valid.
