Just one year into the 10 year initiative, the research team in China is expanding Green Horizons globally, with projects in Johannesburg and Delhi underway. IBM Research-China’s Dr. Jin Yan Shao, Green Horizons’ program manager, talks about her motivations for working on the project, and reaching its lofty goals and expectations.</span><br /><br /><a name="more"></a></div><div align="right"><table align="right" border="1" cellpadding="0" cellspacing="0" class="MsoNormalTable" style="border-collapse: collapse; border: none; margin-left: 6.75pt; margin-right: 6.75pt; mso-border-alt: solid white .5pt; mso-border-insideh: .5pt solid white; mso-border-insidev: .5pt solid white; mso-padding-alt: 0in 5.4pt 0in 5.4pt; mso-table-anchor-horizontal: column; mso-table-anchor-vertical: paragraph; mso-table-left: right; mso-table-lspace: 9.0pt; mso-table-overlap: never; mso-table-rspace: 9.0pt; mso-table-top: .05pt; mso-yfti-tbllook: 1184;"> <tbody><tr style="mso-yfti-firstrow: yes; mso-yfti-irow: 0; mso-yfti-lastrow: yes;">  <td style="border: solid white 1.0pt; mso-border-alt: solid white .5pt; padding: 0in 5.4pt 0in 5.4pt; width: 2.25in;" valign="top" width="216"><div class="MsoNormal" style="mso-element-anchor-horizontal: column; mso-element-anchor-vertical: paragraph; mso-element-frame-hspace: 9.0pt; mso-element-left: right; mso-element-top: .05pt; mso-element-wrap: around; mso-element: frame; mso-height-rule: exactly;"><b style="mso-bidi-font-weight: normal;"><span style="font-family: "HelvNeue Light for IBM",sans-serif; font-size: 13.0pt; line-height: 107%;">About Dr. Jin Yan Shao</span></b></div><div class="MsoNormal" style="mso-element-anchor-horizontal: column; mso-element-anchor-vertical: paragraph; mso-element-frame-hspace: 9.0pt; mso-element-left: right; mso-element-top: .05pt; mso-element-wrap: around; mso-element: frame; mso-height-rule: exactly;"><br /></div><div class="MsoNormal" style="margin-left: .25in; mso-element-anchor-horizontal: column; mso-element-anchor-vertical: paragraph; mso-element-frame-hspace: 9.0pt; mso-element-left: right; mso-element-top: .05pt; mso-element-wrap: around; mso-element: frame; mso-height-rule: exactly; mso-list: l1 level1 lfo1; text-indent: -9.0pt;"><span style="font-family: Symbol; font-size: 13.0pt; line-height: 107%; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol;"><span style="mso-list: Ignore;">·<span style="font: 7.0pt "Times New Roman";">  </span></span></span><span style="font-family: "HelvNeue Light for IBM",sans-serif; font-size: 13.0pt; line-height: 107%;">PhD   in Dynamics Control and Automation from Peking University</span></div><div class="MsoNormal" style="margin-left: .25in; mso-element-anchor-horizontal: column; mso-element-anchor-vertical: paragraph; mso-element-frame-hspace: 9.0pt; mso-element-left: right; mso-element-top: .05pt; mso-element-wrap: around; mso-element: frame; mso-height-rule: exactly; mso-list: l1 level1 lfo1; text-indent: -9.0pt;"><span style="font-family: Symbol; font-size: 13.0pt; line-height: 107%; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol;"><span style="mso-list: Ignore;">·<span style="font: 7.0pt "Times New Roman";">  </span></span></span><span style="font-family: "HelvNeue Light for IBM",sans-serif; font-size: 13.0pt; line-height: 107%;">Joined   IBM in 2007</span></div><div class="MsoNormal" style="margin-left: .25in; mso-element-anchor-horizontal: column; mso-element-anchor-vertical: paragraph; mso-element-frame-hspace: 9.0pt; mso-element-left: right; mso-element-top: .05pt; mso-element-wrap: around; mso-element: frame; mso-height-rule: exactly; mso-list: l1 level1 lfo1; text-indent: -9.0pt;"><span style="font-family: Symbol; font-size: 13.0pt; line-height: 107%; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol;"><span style="mso-list: Ignore;">·<span style="font: 7.0pt "Times New Roman";">  </span></span></span><span style="font-family: "HelvNeue Light for IBM",sans-serif; font-size: 13.0pt; line-height: 107%;">Research   focus: Analytics and optimization algorithms applied to solving challenging   problems for clients and industries, including environmental, energy,   banking, retail, and others.</span></div></td> </tr></tbody></table></div><div class="MsoNormal"><i style="mso-bidi-font-style: normal;"><span style="font-family: "HelvNeue Light for IBM",sans-serif; font-size: 13.0pt; line-height: 107%;">How has Green Horizons progressed in China? </span></i></div><div class="MsoNormal"><br /></div><div class="MsoNormal"><b style="mso-bidi-font-weight: normal;"><span style="font-family: "HelvNeue Light for IBM",sans-serif; font-size: 13.0pt; line-height: 107%;">Jin Yan Shao:</span></b><span style="font-family: "HelvNeue Light for IBM",sans-serif; font-size: 13.0pt; line-height: 107%;"> Green Horizons is a long – 10 year – journey, not just for China, but worldwide.

In the past, forecasts were generated by meteorologists analyzing various data sources, and developing forecasts from there. As the IBM model utilizes all of those sources to make a composite forecast, it makes the process significantly faster. With satellite internet extremely limited, the composite forecast allowed us to use significantly fewer resources to essentially generate a similar result.<b></b></span></div><div class="MsoNormal"><span style="font-family: "helvneue light for ibm" , sans-serif; font-size: 13.0pt; line-height: 107%;"><br /></span></div><div class="MsoNormal"><b style="mso-bidi-font-weight: normal;"><span style="font-family: "helvneue light for ibm" , sans-serif; font-size: 13.0pt; line-height: 107%;">In general, how did cloud cover, or other environmental factors, impact the race?</span></b><span style="font-family: "helvneue light for ibm" , sans-serif; font-size: 13.0pt; line-height: 107%;"> </span></div><div class="MsoNormal"><br /></div><div class="MsoNormal"><span style="font-family: "helvneue light for ibm" , sans-serif; font-size: 13.0pt; line-height: 107%;">JC: In general, weather in the Outback is impacted in two ways: localized ocean-influenced systems near the coasts, and large scale pressure-driven weather systems, throughout. During this event, we saw both types of weather. The most significant impact to the race, though had to be clouds that formed as moist air lifted over the Flinders Range in the last 300 km of the route. With multiple weather forecasts giving differing results, we were able to use all the resources available, and generate a forecast that was better than any one model.</span><br /><br /><span style="font-family: "helvneue light for ibm" , sans-serif; font-size: 13.0pt; line-height: 107%;">Read more about how <a href="http://ibm.co/solarforecasting">solar forecasting</a> was used at the World Solar Challenge, and follow the <a href="http://dme.engin.umich.edu/solarcar25/">UM Solar Team</a>.</span><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh0ZYV81D9QvFb4GieFxZgqrPNHufU71W5Ubbrb600GL9SYi3PeRIBMU8f7OsIsdoEwfzKvIQZhn12ChFdhcR42-250nZG-2Mx8Am7H3Hl7CB7gFvhO3t9wy9dmBQL-tG9gpsAb6uGRHI3V/s1600/clouds_outback.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh0ZYV81D9QvFb4GieFxZgqrPNHufU71W5Ubbrb600GL9SYi3PeRIBMU8f7OsIsdoEwfzKvIQZhn12ChFdhcR42-250nZG-2Mx8Am7H3Hl7CB7gFvhO3t9wy9dmBQL-tG9gpsAb6uGRHI3V/s400/clouds_outback.jpg" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><span style="font-family: "helvneue light for ibm" , sans-serif; font-size: x-small; line-height: 107%;">Clouds over the World Solar Challenge route<br />(photo credit: University of Michigan Solar Car Team and Epik Studios)</span></td></tr></tbody></table></div>
