The sensitivity of the ASCE standardized&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;ET&lt;sub&gt;o&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;equation to meteorological variables from GOES-PRWEB dataset was evaluated for the island of Puerto Rico.

The derived SCs guided the prioritization of bias correction of meteorological data for&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;ET&lt;sub&gt;o&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;estimation from two downscaled climate models (CNRM and CESM). The SCs were applied to evaluate how meteorological variables contribute to model errors and projected future changes in&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;ET&lt;sub&gt;o&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;from 1985–2005 to 2040–2060 at irrigated farms in the south. Both models project a 5.6% average increase in annual&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;ET&lt;sub&gt;o&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;due to projected increases in&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;T&lt;sub&gt;max&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;T&lt;sub&gt;min&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;and a decrease in&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;RH&lt;sub&gt;mean&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;. Despite&amp;nbsp;&lt;/span&gt;&lt;span class="html-italic"&gt;ET&lt;sub&gt;o&lt;/sub&gt;&lt;/span&gt;&lt;span&gt;&amp;nbsp;being most sensitive to relative changes in&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;RH&lt;sub&gt;mean&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;, the contributions from&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;RH&lt;sub&gt;mean&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;T&lt;sub&gt;max&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;, and&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;T&lt;sub&gt;min&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;to future changes in&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;ET&lt;sub&gt;o&lt;/sub&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;are similar.

Study limitations are discussed.&lt;/span&gt;&lt;/p&gt;</dc:description>
