Extract USHCN Monthly Station Data
Description
Monthly minimum temperature, maximum temperature, and precipitation data can be downloaded from the United States Historical Climatology Network (USHCN) website, but these data are in a different format than the one used by HOB Tools. This tool transforms these data into the format used by HOB Tools (i.e., Year / Month / Temp , where each "/" is a tab).
Input
Input File
Select the input file by clicking on "Browse" and navigating to the proper file.
Input Data Format
Data are downloaded from the USHCN website in a compressed format by variable (i.e., mean temperature, precipitation, etc.). Station data in this compressed file are organized in separate files by station number. Therefore, the "ushcn-v2.5-stations.txt" file will need to be consulted to determine the specific station number to extract from this compressed format. The extracted file can then be input into HOB Tools as is for processing.
Start Row
This input is the row number where the main data to be processed begin in the dataset. The start row will be 1 in all cases unless the user has added additional header information to the downloaded dataset. An example of how row numbers are entered is shown in Figure 2 located in the Running HOB Tools topic.
