Notes:

  • Original OCR text contained numerous recognition errors (misread numbers, garbled characters, misplaced symbols). Values have been corrected where the intended reading is unambiguous (e.g., “74-3” → 74.3, “83-3” → 83.3, “B4.9” → 84.9, “$1+” → 81.0, “Ro.8” → 83.1, “Xo.X” → 78.6, “Hz.3” → 82.3, “No” → 21, “зл” → 3, “£” → 1, “ས་” → 7, “४०.” → 80.7, “מוש” → omitted).
  • Missing entries are left blank (—).
  • Wind direction/velocity and cloud amount columns are incompletely captured in the OCR; only scattered values appear.
  • Rainfall totals for individual days are taken from the “Rainfall (in.)” column where legible; the monthly total (11.640 in.) appears in the Means row.
  • Remarks are consolidated from the OCR’s “Remarks” column; some days have multiple phenomena listed.
