Simple Subset Wizard Release Notes
Simple Subset Wizard has been tested with the following browsers:
- Firefox version 3 and later
- Internet Explorer 7 and 8 on Windows XP
- Internet Explorer 8 and 9 on Windows 7
This list covers some of the known problems with the Simple Subset Wizard which will be resolved in future versions:
- All Systems
- Bounding boxes for searches and spatial subsetting that cross the 180-degree meridian are not supported.
- Time-of-day cannot be specified in Date Range values.
- The "Pick a date" calendar tool window can become obscured by the lower menu bar if it is repositioned too high on the screen.
- When selecting data sets from the list of available data sets, if the tree is expanded so that it becomes longer than the height of the screen, each time a data set is selected, the browser may scroll the list upwards in order to bring the "Choose" and "Cancel" buttons into view.
- Some large requests for offline data may be split into multiple orders without warning. In a future release, a warning will be provided if the order will be split, and a choice between proceeding with or canceling the order will be offered.
- It is possible that attempts to subset some data sets will fail because "no data were found matching the criteria of Date Range yyyy-mm-ddT00:00:00Z to yyyy-mm-ddT23:59:59Z, Bounding Box (S,W,N,E): southLat,westLong,northLat,eastLong". This means that although data can be found for the specified date range, none of the data fall within the spatial bounding box. This is more likely to happen for certain data sets when the spatial bounding box is small and the date range interval is short.
- For some data sets that can be subsetted by selected variables, if their are many variables, selecting too many variables can result in a download URL that is so long that it will not work. An attempt to download by using such a URL will result in the error "Request-URI Too Large". This can be avoided by selecting fewer variables to subset. In a future release, a warning will be provided when too many variables have been selected. The data sets for which this problem can be encountered are:
- AIRH2SUP v005
- AIRS2SUP v005
- AIRX2SUP v005
- AIRH3ST8 v005
- AIRH3STD v005
- AIRH3STM v005
- AIRS3ST8 v005
- AIRS3STD v005
- AIRS3STM v005
- AIRX3ST8 v005
- AIRX3STD v005
- AIRX3STM v005
- ML2DGG v003
- When the subset results are viewed for online data, the leading digits of the list entry number are not visible after the 99th entry in the list.
- Internet Explorer 9 on Windows 7
- When the subset results are viewed for online data, each URL in the list may be numbered 0.
- When I Subset Selected Data Sets, a red X indicates "no data were found matching the criteria of Date Range yyyy-mm-ddT00:00:00Z to yyyy-mm-ddT23:59:59Z"
- This happens when no data for that date range is available yet for that data set, and is most likely to happen when the selected date range begins with a recent date. Often, if the search is repeated with the same criteria at a later time, new data in that time range will then be found and subsetted.
- When I Subset Selected Data Sets, a red X indicates "no data were found matching the criteria of Date Range yyyy-mm-ddT00:00:00Z to yyyy-mm-ddT23:59:59Z, Bounding Box (S,W,N,E): southLat,westLong,northLat,eastLong"
- This can happen for certain data sets if the spatial bounding box is small and the date range is short, when data can be found within the date range but not within the spatial bounding box. Often, if the search is repeated with a larger bounding box and/or a longer date range, data will be found and subsetted.
Frequently Asked Questions
When I follow the downloading instructions by downloading a plain text list of URLs to my local workstation and use a Unix command like "wget --content-disposition -i SSW_download_2011‑01‑01T00:00:00_12345_dGoR9Zqq.inp", the downloaded files have names that look like long URLs. How can I download files so that they will have "reasonable" file names?
This can happen when the subsetting is using OPeNDAP (in which case the URL usually contains the string "opendap"), so despite the "--content-disposition" option, each downloaded subset file name is the same as the URL used to download it. A sequence of Unix commands that combine "egrep", "paste", and "awk" can be used to download the files with more reasonable file names.Examine the plain text of URLs to determine what the names of the files (the portion following the last slash of each URL) begin with, and what the extension (the portion just before the question mark that begins with a dot) is. For example, let's say that each name begins with '3B' and the extension is '.nc'. Then use these commands to download the files:
