<p class="MsoNormal">In March 2020, the NASA Giovanni data visualization system will mark its 20<sup>th</sup> year of operation. We are taking this opportunity to have a friendly competition to update our Twitter profile.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">“Giovanni at 20” graphic competition guidelines for <i>nasa_giovanni</i> Twitter profile image.<o:p></o:p></p>
<p class="MsoNormal"><b><o:p> </o:p></b></p>
<p class="MsoNormal">Email submissions electronically to < james.g.acker@nasa.gov >
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Image should be rectangular format; the current image can be viewed at < https://twitter.com/nasa_giovanni/ >. The aspect ratio is ~3:1, width:height. The circular image that appears on each tweet will not be replaced, just the rectangular
profile page banner.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The image should show the use of Giovanni in some Earth science-related manner, and should be somewhat self-explanatory (the current image shows a true-color image of California wildfire smoke and a Giovanni-generated map of aerosol optical
depth data showing the smoke plume.)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">These text elements must be incorporated: “Giovanni”; “20<sup>th</sup>” OR “20<sup>th</sup> Anniversary” OR “2000-2020” (superscripting not required); and “NASA” (Do
<u>NOT</u> use the NASA “meatball” logo). A short legible caption of what the image depicts can also be included.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Judging criteria will be scientific content, artistic merit, and incorporation of the required text elements. The staff of the GES DISC will select the image for the new banner from the submissions.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The author of the image will be eligible to receive a few items of NASA scientific materials, including a 2020 NASA science calendar. These items will be mailed, so a real mailing address will be necessary to receive them. (Communication
will be by email for privacy; name will only be revealed if the author allows it to be released.)<o:p></o:p></p>
