Site log - Houston (Sept 1999) Flags: 1-Satellite coincidence data 2-Scan in TSDIS data A-Major problem (moderate to strong AP > 25 dBZ &/or widespread coverage > 10%) B-Minor problem (weak AP &/or very litte coverage) ******************************************************************************* 01 Sep 99: Almost continual procession of scattered convection and organized convective systems. Precip rotates around a central of circulation that seems to drift to NNW throughout the day. Precip increases significantly in areal coverage over the Gulf after 07Z. Most precip over Gulf dissipates near 16Z, but scattered, small convective cells form over land afterwards. A multicell complex forms directly N of radar after 1930Z. TRMM overpass at 1553Z captures stratiform region left over from previous convective system. Data processed: 0001-2359Z Sat.

A convective band forms to N of radar (line oriented N-S) early on and persists thru 09Z. Training of moderate to heavy precip over same locations probably causes significant precip accumulations. Precip largely dissipates &/or moves out of scope by 12Z w/ only a few isolated cells w/in 150 km range. Broken convection moves in from NW along an outflow boundary late in the day.

Precip gradually builds in areal coverage as a few convective clusters form. A few clusters later in the day develop decent stratiform shields. By far, the most significant precip event in the past couple of weeks. TRMM overpass near 0233Z caputres a few scattered cells in SE sector. Data processed: 0003-2349Z Sat.

Convective clusters to NW and SW & stratiform region to E at 00Z. Convection to SW moves to NNE, constantly regenerating a N-S oriented convective line and a large trailing stratiform region. By 06Z, a convective line (oriented NE-SW) moves in from N and NW, eventually clashing with the pre-existing convective cluster that originated in the SE sector early in the day. By 10Z, a large swath of precip extends across the radar scope...mostly stratiform w/ some intense embedded convective cores. By 15Z, most of the convection has ceased, leaving behind a broad region of light to moderate stratiform in the S half of the scope. The stratiform shield gradually dissipates/moves off by 22Z Data processed: 0000-2348Z Sat. Coincidence: 0121Z(315 km), 0257Z(521 km), 2054Z(67 km), 2231Z(583 km) QC notes: 0441-1459Z: Perhaps some CAE mixed in w/ precip. Algorithm seems to do decent job 1B, 2B !!FLAG!! with the most obvious CAE, but 1A, 2A !!FLAG!! there may be some light patches of contamination. Also some VOSs w/ intense, small embedded clutter specks. Also appears to be some holes punched in precip by default params, but this problem is largely corrected. 1737Z, 1757-2022Z, 2042Z: CAE to NE, + light precip to SSE. ----> Corrected. % of data reprocessed: 114/277 = 41% ************************************************************************** 30 Sep 99: Dry.
