Tmi files

RFI occurs in large regions where geostationary tv broadcast or telecommunication signals in the microwave range reflect off the ocean and are observed by the radiometer. RFI can also occur in small regions due to emitting sources on the surface where microwave-range signals are used. The RSS TMI data are provided as daily maps separated into ascending and descending orbit segments , 3-day mean maps, weekly mean maps and monthly mean maps. All images cover a global region with valid data extending from 40S to 40N at a pixel resolution of 0.

The files contain no headers or metadata and are a simple set of single-byte arrays. Since the data are stored as single bytes, no byte-swapping is needed when transferring between computers. These gridded data are organized according to observation date. The data products include daily and time-averaged geophysical data as follows:. There are gaps within these data. Missing data generally affect Daily and 3-Day products, but can also reduce the number of observations and thereby the quality in Weekly and Monthly averages.

Data gaps are generally due to missing data upstream from our processing facility, such as the instrument being turned off. There are two cases for which neighboring data swaths overlap. At higher latitudes, orbit segments overlap within local regions and within a short measurement time.

In the second case, there is a "seam" on each map where the first and last orbit segments of the day overlap. Data at this seam are not averaged.

Here, the last data from the day overwrite the first data measured at the beginning of the day. Each daily file name has the convention: yyyymmddv7. The center of the first cell of the column and row map is at 0. The center of the second cell is 0. The data values fall between 0 and Specific values have been reserved:.

The data values between 0 and need to be scaled to obtain meaningful geophysical data. To scale the data, multiply by the scale factors listed in the table above:. They consist of six maps with a grid size of 0. Each file can be read as a ,,6 array.

There are only six maps because the Time layer is omitted. All other parameters are present and in the same order. All binary data files have zip compression to reduce size and decrease transfer time.

If you only need one file, use the "Download Binary Data" button on the web page. If you are accessing a large number of files, it may be more convenient to use our anonymous ftp server: ftp.

All data for a given map were collected on that specific GMT date. The date at which the observation was made with respect to local time may vary depending on the grid longitude. The graphic image maps were produced from public V7. Previous file extension TIX file extension. Next file extension file extension TMS.

You will need a program compatible with the specific file you are trying to open, as different programs may use files with file extension TMI for different purposes. While we have not verified the apps ourselves yet, our users have suggested 2 different TMI openers which you will find listed below. These apps are known to open certain types of TMI files. Remember, different programs may use TMI files for different purposes, so you may need to try out a few of them to be able to open your specific file.

Try a universal file viewer like Free File Viewer. It can open over different types of files - and most likely yours too. Download Free File Viewer here.
