|a In preparation for the launch of TRMM, new algorithms must be
|
| 520 |
|
|
|a created that take advantage of the combined data from radar
|
| 520 |
|
|
|a and microwave radiometers that will be on board the
|
| 520 |
|
|
|a satellite. A microwave radiative transfer algorithm with a
|
| 520 |
|
|
|a one-dimensional cloud model is created that incorporates data
|
| 520 |
|
|
|a from radar and radiometers using data obtained from TCM90 and
|
| 520 |
|
|
|a TOGA-COARE flown over the western Pacific in 1990 and 1993,
|
| 520 |
|
|
|a respectively. First, a convective cloud model (CCM) was
|
| 520 |
|
|
|a created that contained a CLW distribution and vertical rain
|
| 520 |
|
|
|a rate structure that were common in previous studies. The
|
| 520 |
|
|
|a brightness temperature - rain rate (T-R) relationships
|
| 520 |
|
|
|a generated by the CCM are shown to produce warmer brightness
|
| 520 |
|
|
|a temperatures at low rain rates and lower brightness
|
| 520 |
|
|
|a temperatures at high rain rates than the Wilheit et al.
|
| 520 |
|
|
|a (1977) model (WILM) and TOGA-COARE observations. Next, a
|
| 520 |
|
|
|a hybrid cloud model (HCM) was developed using observations
|
| 520 |
|
|
|a from TOGA-COARE, TCM-90, and other field projects.
|
| 520 |
|
|
|a Observations changed the cloud model in four ways. First,
|
| 520 |
|
|
|a stratiform clouds with low rain rates were shown to have a
|
| 520 |
|
|
|a low CLW content (< 0.1 g M-3). Second, radar data showed a
|
| 520 |
|
|
|a linear decrease in the logarithm of the backscatter of ice
|
| 520 |
|
|
|a particles above the freezing level. Third, tropical clouds
|
| 520 |
|
|
|a contained more small drops and fewer large drops than
|
| 520 |
|
|
|a predicted by the Marshall - Palmer drop-size distribution
|
| 520 |
|
|
|a (DSD). Last, the reflectivity of ocean surface appears to
|
| 520 |
|
|
|a be specular. The T-R relationships generated by the HCM are
|
| 520 |
|
|
|a different from the CCM. The HCM predicts colder brightness
|
| 520 |
|
|
|a temperatures at low rain rates than in the CCM because of a
|
| 520 |
|
|
|a low CLW content in the cloud at rain rates < 5 mm h-1. At
|
| 520 |
|
|
|a higher rain rates, the vertical precipitation structure and
|
| 520 |
|
|
|a DSD above the freezing level in the HCM make the cloud
|
| 520 |
|
|
|a transparent to microwave radiation resulting in warmer
|
| 520 |
|
|
|a upwelling brightness temperatures at each frequency. The
|
| 520 |
|
|
|a brightness temperatures generated by the HCM closely agree
|
| 520 |
|
|
|a with observations from TOGA-COARE. This study shows that a
|
| 520 |
|
|
|a plane-parallel microwave radiative transfer algorithm coupled
|
| 520 |
|
|
|a with a cloud model based on microphysical observations can
|
| 520 |
|
|
|a accurately simulate rainfall observed in the tropics.
