MAHTE Climatology Complete Dataset

<p>This dataset contains information for all Mesoscale Airmasses with High Theta-e (MAHTEs) collected from the Automated Surface Observing System (ASOS) for the period of January 2000 through June 2022. Data are provided in a .csv file, with each row corresponding to an individual MAHTE. Each column corresponds to one of the following data points:</p> <ul> <li>station: four letter code corresponding to the ASOS station where the MAHTE was identified</li> <li>index:&nbsp; line within the monthly ASOS text file where the MAHTE was identified (after erroneous/incomplete lines have been removed)</li> <li>datetime: date/time of MAHTE identification</li> <li>mahteflag: series of internal flags detailing MAHTE identification process, appearing in the following order <ul> <li>w1: indicates passage of wind test</li> <li>t1: indicates passage of thermodynamic tests</li> <li>r0/r1: indicates a retrograding/progressive MAHTE, respectively</li> <li>s1: indicates passage of size test</li> <li>w1: unused relic of previous algorithm version</li> </ul> </li> <li>dthte: change in theta-e across the boundary (cool side &mdash; warm side, regardless of MAHTE orientation)</li> <li>dtemp: change in temperature across the bounary (cool side &mdash; warm side, regardless of MAHTE orientation)</li> <li>u0: ground speed of boundary</li> <li>width: width of MAHTE</li> <li>duration: residence time of MAHTE over the ASOS station</li> <li>thermodelay: time required to obtain the required thermodynamic shift for passage of thermodynamic tests (0 = five minutes, 1 = ten minutes)</li> <li>envdwptdep: dew point depression on the warm side of boundary</li> <li>mahtedwptdep: dep point depression within the MAHTE</li> <li>mahtecape: Convective Available Potential Energy (CAPE) within the MAHTE</li> <li>envcape: CAPE on the warm side of the boudnary</li> <li>mahte06bwd: 0-6 bulk wind difference within the MAHTE</li> <li>env06bwd: 0-6 bulk wind difference on the warm side of the boundary</li> <li>ddwpt: change in dew point depression across the boundary (warm side &mdash; cool side, regardless of MAHTE orientation)</li> </ul> <p>&nbsp;</p>
