 name=Naerstad Model
 usage=The following input data are required:\nobservations - array of weather observations. An observation consists of:\n\ttimeMeasured - timestamp for observation\n\telementMeasurementTypeId - Code for parameter\n\tlogIntervalId: 1 for hour value\n\tvalue: the observed value\nFour different weather parameters should be provided:\n* TM - Mean temperature (Deg. Celcius)\n* RR - Aggregated rainfall (Millimeters)\n* Q0 - Global radiation (Wh/m2)\n* BT - Leaf wetness\nThey should all be hourly values, they should all be complete hourly series in the exact same period. \nMinimum period length is 4 days (TODO: Verify!)\nThe following input data are optional:\ncalculationStart - the time when calculation should start\ncalculationEnd - the time whe calculation should end \n
-description=The N\u00e6rstad model\n\nThe N\u00e6rstad potato late blight forecasting model predicts how conducive the weather is for spore production and subsequent spore release, spore survival and infection. The model consists of sub models for the different steps in the disease cycle like spore production, spore release, spore survival and infection of spores. The model's criteria for spore production are long humid periods and at moderate humidity sporulation is reduced. The amount of viable attached sporangia is reduced by drought, and some spores are washed off during rain. The model criteria for spore release into the air are a drop in humidity or increased radiation, but the release is inhibited by high leaf wetness. The model includes criteria for spore survival and the viability of released spores is strongly inhibited by solar radiation. The spore load is also reduced by precipitation. The criteria for infection are that the leaf wetness duration has to be sufficient for the spores to germinate and infect. The risk of blight development is a function of the amount of viable released spores and the duration of leaf wetness.\n\nThe N\u00e6rstad model has been developed by Ragnhild N\u00e6rstad

+description=<p>The model is based on several years of experiments where trap plants have been placed next to a potato field infected with late blight. Infections on these plants have been correlated with weather conditions the day of exposure, and this is the data the model is based on. The model predicts if there are favourable conditions for spore production and the following spread, survival and infection of these spores. The model produces an infection risk, and a value of 2.5 corresponds to one spot of late blight on each trap plant exposed. This value of 2.5 is the threshold where the model issues a warning.</p>\n<h3>Data</h3>\n<p>The model uses hourly values of the following parameters as input:</p>\n<ul>\n<li>Air temperature</li>\n<li>RH</li>\n<li>Precipitation</li>\n<li>Wind speed (2 m height)</li>\n<li>Wind speed (10 m height)</li>\n<li>Net radiation</li>\n<li>Short wave radiation</li>\n<li>Leaf wetness</li>\n<li>VPD (0.61078*EKSP(17.269* TM /(TM +237.3)), k)P</li>\n</ul>\n<h3>Spore production, dissemination and survival</h3>\n<p>The VPD needs to be under 220 Pa (RH&gt;approximately 90%) for at least 87 degree hours to initiate spore production. Number of spores increase with duration of the period with high humidity. A VPD between 220 and 520 Pa reduce the spore production, and a VPD higher than 520 will stop it completely.</p>\n<p>Spores are discharged into the air when the RH decreases, and free water on the leaf surface will inhibit spore release. Rain will wash the spores off, and sunlight will kill a large number of the released spores.</p>\n<h3>Risk of late blight infection</h3>\n<p>The spores need free water to start growing, either from rain or dew. The leaves need to stay wet for at least 40 degree hours for the spores to have time to both start growing and infect. The amount of spores able to infect increases with the duration of the wet period.</p>\n<p>Risk of late blight infection is calculated as follows:</p>\n<p>Risk = (TSWH(t) /40)*VRS(t) *IR(t) TSWH(t) = temperature sum for wet hours</p>\n<p>VRS(t) = viable released spores IR(t) = Infection risk (=1 when TSWH(t)&gt;=40)</p>\n<p>Interpretation of the model output</p>\n<p>Risk &lt; 1 = no warning Risk &gt; 1 and &lt; 2,5 = possible warning coming up if conditions persists Risk &gt; 2,5 = warning issued</p>\n<p>When a warning is issued, any control measure should be considered based on cultivar resistance, chyoice of fungicide and time of last application. Risk of infection is highest after several consecutive days with warnings, and especially if late blight has been observed in the area.</p>\n<p>{{filename="/images/chart.png" description="Eksempel p&aring; varsel"}}</p>
