Tropical Western Pacific–International Cloud Experiment » Data


NOAA datasets from TWP-ICE are available on ESRL/PSD's ftp server at:

Documentation for each dataset is also available on the ESRL/PSD ftp server and describes dataset format, calibration, and images of the data. You can find the NOAA datasets and documentation are available in the following sub-directories:

Instrument Type FTP location Documentation
Rain Gauge /rain_gauge/ PDF
Joss-Waldvogel Disdrometer /jwd_disdrometer/ PDF
S-Band Profiler /s_band_profiler/ PDF

Additional Notes

Since the TWP-ICE field campaign was sponsored by DOE, the NOAA datasets, as well as other datasets collected during MC3E, can be found on the DOE/ARM TWP-ICE web page.
