详细信息----------Details----------
The nine "real" cases are forecast model output from three different versions of the Weather Research Forecast (WRF) model denoted "wrf2caps", "wrf4ncar" and "wrf4ncep" (see Kain et al. 2008; Ahijevych et al., 2009 for complete details), and the corresponding "observed" fields are stage II reanalyses denoted here by "obs". The models are 24-h forecasts so that the valid time is for the next day (e.g., obs0426 corresponds with wrf2caps0425). The final four digits for the "real" cases give the month and day of the forecast/observation. These data were from the 2005 Spring Program of the Storm Prediction Center/National Severe Storms Laboratory (SPC/NSSL, cf. Weiss et al., 2005; Kain et al., 2008). Units for the real cases are in mm/h, and are on the NCEP g240 grid (~4-km resolution) with 601 X 501 grid points. Both SPC and NSSL should be cited as sources for these cases, as well as Weiss et al. (2005) and possibly also Kain et al. (2008). The data were made available to the ICP by M. E. Baldwin.
9“真实”的情况下，预测模型输出的天气研究预报（WRF）模型表示为“wrf2caps”，“wrf4ncar”和“wrf4ncep”（见凯恩等人，2008年从三个不同的版本，Ahijevych等，2009年的完整详细信息），以及相应的“观察”的领域是第二阶段的再分析这里表示“OBS”。该机型是24小时预报，有效时间为次日（例如，obs0426的对应wrf2caps0425）。最后四位数为“真正”的情况下给的月份和日期的预测/观察。这些数据是从2005年春季计划的风暴预测中心/国家强风暴实验室（SPC / NSSL，比照Weiss等人，2005;凯恩等人，2008）。真正的情况下，单位是毫米/小时，和NCEP G240电网（约4公里分辨率）601 X 501个网格点。 SPC和NSSL的引用应为在这些情况下，源以及Weiss等人。 （2005），也可能凯因等。 （2008年）。数据进行了ME鲍德温的ICP。
The five geometric cases are simple ellipses (each with two intensities) that are compared against the "observed" case (geom000) on the same NCEP g240 grid as the nine real cases. See Ahijevych et al. (2009) for complete details. Case geom001 is exactly the same as geom000, but is displaced 50 grid points to the right (i.e., ~200 km too far east). Case geom002 is also identical to geom000, but displaced 200 grid points to the right. case geom003 is displaced 125 grid points to the right, and is also too big 9i.e., has a spatial extent, or coverage, bias). Case geom004 is also displaced 125 grid points to the right, but also has a different orientation (note, however, that it is not a true rotation of geom000). Case geom005 is displaced 125 grid points to the right, and has a huge spatial extent bias. This last case is also the only one that actually overlaps with geom000, and therefore may be regarded by some as the best case. It is certainly the case that comes out on top by the traditional verification statistics that are calculated on a grid point by grid point basis. Ahijevych et al. (2009) should be cited if these geometric cases are used for publications, etc.
五个几何情况下，简单的省略号（每两个强度）对“观察”的情况（geom000）在同一NCEP G240电网的九个真实案例，进行比较。请参阅Ahijevych等。 （2009）的完整的详细信息。案例geom001是完全一样geom000的，但流离失所的权利（即约200公里，也远东）的50个网格点。案例geom002是相同geom000，但流离失所的200个格点的右侧。情况下geom003流离失所的125个网格点的权利，也太大9i.e.，有一个空间范围，或覆盖，偏置）。案例geom004网格点125也移位到右侧，但也有不同的方向（注意，然而，它不是一个真实的旋转geom000）。案例geom005流离失所的125个网格点的权利，有巨大的空间范围的偏差。这最后一种情况是唯一的一个，实际上与geom000重叠，因此可能会被一些最好的情况下。这是肯定的情况下，由传统的验证统计数据，计算网格上的网格点基准点之上。 ahijevych等。 （2009年），如果这些几何的情况下，应引用于出版物等。
The seven perturbed cases (dented here by pert00X) are perturbations of pert000, which is adapted from wrf2caps0531 (again, see Ahijevych et al, 2009 for more details). Case pert001 shifts pert000 three grid points to the right, and five grid points down (i.e., ~12 km to the east and ~20 km to the south). Case pert002 is a shift six points to the right, and ten points down. Case pert003 is a shift 12 points to the right and 20 points down. Case 4 is a shift 24 points to the right, and 40 points down. Case pert005 is a shift 48 points to the right and 80 points down. Case pert006 is a shift 12 points to the right, and 20 points down, and the entire field is multiplied by 1.5. Case pert007 has the same spatial displacements as pert003 and pert006, but also subtracts 1.27 from the entire field. Ahijevych et al. (2009) should be cited if these perturbed cases are used for publications, etc.
7扰动的情况下，（凹陷这里pert00X）是扰动为pert000，这是适应从wrf2caps0531（再次说明，有关详细信息，请参阅Ahijevych等人，2009年）。案例pert001转移的权利，pert000 3个网格点和五格分的情况下（即~12公里的东部和~20公里的南部）。案例pert002是转变的权利，6分，10分的情况下。案例pert003是转变12分的权利和20分的情况下。案例4是移24点到右边，和40分的情况下。案例pert005是转变的权利和48分，80分的情况下。案例pert006是一个此消彼长的权利，12分和20分的情况下，整场乘以1.5。案例pert007具有相同的空间的位移作为pert003和pert006，但也减去1.27从整个字段。 ahijevych等。 （2009年）的引用应，如果这些扰动的情况下，用于出版物等。
The longitude and latitude information for each grid (the NCEP g240 grid) is contained in the ICPg240Locs dataset.
在ICPg240Locs数据集包含每个网格的经度和纬度信息（NCEP G240电网）。
These constitute all of the official data test cases used for the first round of the ICP, and in the special collection of papers for Wea. Forecasting. Other data sets for the ICP can be obtained from the ICP web site (http://www.ral.ucar.edu/projects/icp). Future data sets for the next round of the ICP will also be available there, and may potentially also be made available here.
这些构成了所有的官方数据测试情况下，在第一轮的ICP，为WEA的特备收集的论文。预测。其他各组数据的ICP可以从的的ICP网站（http://www.ral.ucar.edu/projects/icp）。未来的数据集，为下一轮的ICP也有，而且也可能会提供在这里。
