[1] The Tropical Rainfall Measuring Mission (TRMM) version-6 rainfall products show the reduced bias between Precipitation Radar (PR) and TRMM Microwave Imager (TMI) rainfall estimates during the 1997/1998 El Niño event noted in version 5, but need to be verified. We investigate consistency between TMI-observed brightness temperatures (TBs) at 10 and 19 GHz channels and those simulated from the...
[1] Hourly averaged precipitation rates from an ensemble of the Community Climate Model version 3 (CCM3) simulations for the 44-month period from January 1998 through August 2001 are compared to observations from the Tropical Rainfall Measuring Mission (TRMM) satellite. In order to have adequate sampling by the satellite, comparisons are made for 15 longitude 10 latitude boxes and for larger ge...
This paperwork describes a comprehensive statistical assessment of rain gauge and satellitebased monthly and annual rainfall measurements over Nigeria during the period of 2001 to 2010. Two statistical methods were empolyed for inter-comparison and validation of the Tropical Rainfall Measuring Mission TRMM 3B43 V7 rainfall product. TRMM was selected because of the recently developed algorithms ...
Droughts are one of the most damaging climatic phenomena, and the most complex natural hazard which affects the economy, agriculture, public health and environment in large areas. The aim of this study is to compare drought indicators derived from tropical rainfall measuring mission (TRMM) data in the south of Iran. Also the TRMM rainfall was considered, so as to investigate changes in the rai...
We assess the water balance of the Brazilian Cerrado based on remotely sensed estimates of precipitation (TRMM), evapotranspiration (MOD16), and terrestrial water storage (GRACE) for the period from 2003 to 2010. Uncertainties for each remotely sensed data set were computed, the budget closure was evaluated using measured discharge data for the three largest river basins in the Cerrado, and the...
[1] This study uses TRMM lightning and radar observations to study the fundamental relationship between precipitation ice mass and lightning flash density. The results indicate that the physical assumptions of precipitation-based charging and mixed phase precipitation development are robust and that on a global scale, the relationship between precipitation ice water path and lightning flash den...
در قرن اخیر یکی از مهمترین چالشهای جهان، خشکسالی بوده، پایش و ارزیابی شدت و مدت آن برای مقابله و کاهش اثرات آن بسیار ضروری است. در چند دهه اخیر با توسعه و پیشرفت مباحث سنجش از دور، برآوردهای ماهوارهای خشکسالی با دقت مکانی بالا و گامهای زمانی مختلف بهطور گسترده مورد استفاده قرار گرفته است. لذا هدف پژوهش حاضر، تحلیل خشکسالی هواشناسی و توزیع خطای برآوردی دادههای ماهواره TRMM با دادههای ...
